Police are investigating an alleged assault at the venue where former Labour MP Keith Vaz made his return to politics.
On Tuesday, Mr Vaz was elected chairman of the Leicester East Constituency Labour Party (CLP) at a meeting attended by around 150 people.
He stood down as MP for the seat at the last general election, having represented the constituency since 1987.
It came after Mr Vaz was given a six-month Commons ban over drug allegations involving sex workers at his flat.
Leicestershire Police has said it is looking into an allegation of assault at the venue where Mr Vaz’s election as chairman took place.
A spokeswoman for the force said: “We can confirm we received a report of an assault at the Belgrave Neighbourhood Centre yesterday evening.
“There are further investigations being carried out into the alleged assault to see if any criminal offences have occurred.”
A Labour activist complained to police of an injury to her right wrist as she tried to get into the meeting, Leicestershire Live reported.
It is understood that Claudia Webbe, who succeeded Mr Vaz as MP for the constituency, was not at the meeting due to parliament sitting at Westminster.
The six-month ban handed to Mr Vaz was the longest ever given to an MP.
A parliamentary inquiry investigated claims contained in a Sunday Mirror article back in 2016 that he offered to purchase cocaine for male sex workers while posing as an industrial washing machine salesman called Jim.
Mr Vaz was chairman of the Home Affairs Select Committee at the time – and the committee was looking at the issues of drug use and prostitution.
He complained of suffering from amnesia and told investigators the men were decorators.
However, parliament’s standards watchdog dismissed his explanation as “incredible” and “frankly ludicrous”.
