An Israeli accused by the US of hacking attacks has been released by British authorities due to a misunderstanding

An Israeli private investigator arrested on charges of hacking attacks on an unnamed U.S. lobbying firm was acquitted because of a procedural error, British officials said Thursday.

Amit Forlitt was detained at London’s Heathrow Airport on April 30 at the request of US authorities, who accused him of involvement in a hacker attack scheme to gather information on Argentina’s debt default dispute.

But England’s National Crime Agency said he “did not appear in court within the stipulated time due to a misunderstanding”.

“The judge dismissed his case and he was released,” the company said in a statement.

British prosecutors confirmed in a statement that the case against Forlitt had been dropped and “there are therefore no charges against him at this time”.

Reuters was unable to locate Forlit’s current location. His lawyers in the U.S. — where he faces a separate lawsuit related to other hacking allegations — did not return messages seeking comment.

In previous conversations with Reuters, Forlit denied being a hacker.

The US Department of Justice and the FBI declined to comment. Speaking in a British court last week, a U.S. attorney said a Washington lobbying and public relations firm paid $20 million to one of Forlitt’s companies for information “regarding the Argentine debt crisis.”
