Two men, believed to be Israelis, who were arrested on a British Airways flight to Heathrow on Monday, have been released without charge.

The men were said to have made threatening remarks about the plane's destination and acted “disruptively” during a flight from Las Vegas.

They were arrested when the plane landed in Britain but the Metropolitan Police confirmed on Tuesday morning that they had been released.

It had been claimed that the men made “inappropriate and potentially threatening comments regarding Iran and the possible route of the aircraft”.

A Met spokesman said there was no indication they had posed any danger to the plane or its passengers.

He could not confirm whether the men were Israeli as full nationality checks had not taken place before their release.
