Strangers’ Bar staff have been called to Belgravia Police Station at 3pm to give further witness statements about the Eric Joyce brawl. Other MPs who witnessed the affair, as well as staffers and other drinkers will also be interviewed in the coming hours.

Guido understands that the really bad news for Eric Joyce is that as many as eight officers witnessed him breaking out of police custody to return to the fray. Police sources indicate that the main headbutting incident happened after the police had first intervened. All of the officers have given statements this morning. There is further bad news for Joyce in the fact that one of the victims, possibly Tory MP Stuart Andrew, was left concussed from the incident, meaning that the charge could be Actual Bodily Harm rather than assault. And that’s by-election territory…

UPDATE: ITV’s Alex Forrest says the Members are being interviewed in their Westminster offices.
