A Chappaqua couple faces felony charges after authorities say they extorted millions of dollars in a complex larceny-by-extortion scheme involving lies about CIA connections, reconnaissance missions to Honduras and Polish priests attempting to infiltrate the U.S. Government.

Vickram Bedi, 36, and his girlfriend Helga Ingvarsdottir, 39, both Chappaqua residents, were arrested by Harrison Police Thursday while preparing to leave the country, authorities said. The couple extorted money from a single victim for six years—from August 2004 to October 2010—through Datalink Computers, their computer service business in Mount Kisco, according to the Westchester County District Attorney's office.

Harrison police estimate the total amount taken in the scam to be $20 million.

The victim, widely reported as Roger Davidson, 58, is noted, according to the Westchester County District Attorney's office, as "the great-grandson and great grand-nephew of the two brothers who founded Schlumberger Ltd." which is an oilfield services company. He is also described as a "noted pianist and composer."

The couple came into contact with Davidson in 2004, after he developed a virus on his computer. Fearing that all of his documents and music, which were stored on the computer, would be lost the Davidson brought his computer to the couple's business for repairs, authorities say.

At that point authorities say that Bedi and Ingvarsdottir worked together to concoct a scheme to extort the money.  

Authorities say Bedi told Davidson that his computer had been specifically targeted and that he and his family were in grave danger. Bedi allegedly explained that he had the money, contacts and overall resources to track down the source of the virus if Davidson cooperated. Bedi used the story to convince Davidson to not only pay for computer retrieval equipment, but for protection from the fictional group as well, according to the Westchester County District Attorney's office.

In a string of far-fetched lies, the pair used fear tactics to convince Davidson to make monthly payments to Datalink from his American Express card, authorities say.

During the six-year period Bedi told Davidson that he had traced the source of the virus to a hard drive in a remote area of Honduras, according to a press release. Authorities believe Bedi told Davidson that he had sent his uncle—whom Bedi claimed was an operative in the Indian Military—on a successful reconnaissance mission to retrieve the drive.

Bedi further claimed that his uncle obtained classified information that Polish priests affiliated with Opus Dei were attempting to possibly harm Davidson. Bedi also told Davidson that the Central Intelligence Agency had subcontracted him to prevent attempts by those Polish priests to infiltrate the United States Government, all according to a press release from the Westchester County District Attorney's office.

"As is charged in the complaint, these two defendants preyed upon, duped and exploited the fears of this victim with cold calculation and callousness," District Attorney Janet DiFiore said in a media release. "The systematic method with which they continued the larceny over a period of more than six years is nothing short of heartless."

Davidson is a composer and pianist who is also founder and president of a group called Universal Sacred Music, which he has performed with. His connection with Bedi and Ingvarsdottir became extensive, reaching a point where the two were even part of the music organization. According to the Icelandic newspaper Fréttablaðið, Bedi and Ingvarsdottir served respectively as vice president and treasurer on the board of directors. In a YouTube video of a 2006 performance, Davidson is shown with Bedi standing by his side, The Wall Street Journal reported.

The heir even named Bedi as his co-trustee for a financial trust. In January the two filed suit against Wachovia, claiming that the bank "browbeat" him into an investment that was a "volatile basket," which they claim cost $12.5 million, according to the complaint and Courthouse News Service. A copy of the complaint can be found here.

Harrison police became suspicious in late August when two Purchase residents reported finding GPS devices attached to their vehicle. Police believe that the Purchase residents were being watched because Davidson was told they were associated with the international group out to get him.

"Part of the scam was the victim was led to believe the people in Purchase were out to kill him," said Harrison Police Chief Anthony Marraccini. "He had private protection or security that might have placed those devices on those cars."

Information from that incident jump-started the two and a half month investigation that eventually led Harrison police to Bedi and Ingvarsdottir.

Police arrested Ingvarsdottir on Thursday at about 12:30 p.m. while she was out shopping, Marraccini said. Bedi was arrested at his home later that day. The couple had been out of the country just before the arrest, and police were waiting for them to return.

Although in the United States legally, Ingvarsdottir is an Icelandic citizen. Police had been concerned that the couple wouldn't return to the United States and moved quickly when they learned both had returned to the country for a meeting.

"They left the country abruptly, and we were waiting for them to return," said Marraccini. "When they did return we took advantage of that and made the arrest."

Search warrants were executed at the couple's home at 38 Hollow Oak Rd. in Chappaqua, as well as Datalink Computers at 165 Main St. in Mount Kisco, Harrison Police said Monday.

Police seized more than $150,000 in cash as well as vehicles and jewelry during the search of the couple's home. Business records supporting the case were found at Datalink, Marraccini said. Police also froze Bedi and Ingvarsdottir's bank accounts and seized numerous properties owned by the couple. 

Both suspects were arraigned in Mount Kisco court and are being held in Westchester County Jail on $3 million bail. The couple have surrendered their passports and a temporary order of protection for the victim has been awarded, according to the Westchester County District Attorney's office.

Both are charged with first degree grand larceny—a class B felony. If convicted both face eight and a third to 25 years in prison.

Requests by Patch  for comments from two people working at Datalink on Monday afternoon were declined.

Helga Ingvarsdottir is the daughter of Ingvar Karlsson, a wealthy businessman in Iceland, police said. She is also the granddaughter of Karl Karlsson, founder of trading company K. Karlsson, according to Fréttablaðið reporter Sunna Valgerðardóttir. 

The investigation remains open at this time. Marraccini said that "absolutely there are" other people possibly involved as police continue to search for leads.

Ingvarsdottir and Bedi are due in Mount Kisco court on Dec. 2.
