Former U.K. envoy to Washington Peter Mandelson was released on bail Tuesday after being arrested in London on suspicion of misconduct in public office and ties to Jeffrey Epstein.

Mandelson, 72, was ⁠fired from the most prestigious posting in Britain's diplomatic service ⁠in September, when the depth of his friendship with the convicted sex offender started to become clear.

Police earlier this month began a criminal investigation into Mandelson after Prime Minister Keir Starmer's government passed on communications between the former ambassador and Epstein.

"Officers ​have arrested a 72-year-old man on suspicion of misconduct in public office," London's Metropolitan Police said in ​a ⁠statement relating to an investigation into a former government minister.

Mandelson was filmed leaving his central London home Monday afternoon. He was accompanied by plainclothes officers wearing body cameras before being driven away in a car.
