The Metropolitan Police have confirmed that Eric Joyce will face no further action in connection to an incident in a House of Commons bar on March 14.
The Falkirk MP was arrested on suspicion of assault following an alleged late-night fracas in the Sports and Social Club in Westminster.
After spending a night in the cells at Belgravia police station, the original charge was dropped and he was re-arrested on suspicion of causing actual bodily harm.
That charge has now also been dropped.
Joyce announced on his Twitter feed today that he faced no further action.
A Met spokesman confirmed that a man aged in his fifties, arrested on March 14 on suspicion of assault and ABH, would not face prosecution.
Eric Joyce was first elected as MP for Falkirk West in 2000 as a Labour member. He was re-elected in 2001 and again in 2005 and 2010 for the enlarged Falkirk constituency.
Last March, he was fined £3000 after he admitted headbutting two Tory MPs and assaulting a Labour Whip and Tory councillor during an incident in the Strangers’ Bar in Westminster.
He was also given a 12-month community order which barred him from licensed premises for three months and placed him on a weekend curfew.
Following that incident, he resigned from the Labour Party and announced he would not seek re-election at the 2015 General Election.
