A Met police spokesman said: “Police were called shortly before 10.30pm this evening to reports of a disturbance at a bar within the House of Commons.
“Officers attended and a man in his 50s was arrested in connection with this incident. He remains in custody and inquiries continue.”
Joyce, who quit the Labour party last year after headbutting Tories Stuart Andrew and Ben Maney in another incident, is reported to have got into a fight during a karaoke night in the Sports and Social bar.
According to reports in The Independent eyewitnesses claim to have seen Joyce wrestling on the floor with officers with a “policeman’s helmet being knocked off” in the process.
The former soldier was fined £3000 and was ordered to pay his victims £1400 after he pleaded guilty to common assault last year.
In a statement to the Commons on 12 March last year he apologised to his victims but said that he intended to finish his term as an MP.
