The Labour Party has suspended MP Dan Norris after “being informed of his arrest”, a party spokesman has told the BBC.
The suspension means Mr Norris, the MP for North East Somerset and Hanham, is also understood to have had the party whip suspended, meaning he is not able to sit as Labour MP in the Commons.
The Labour party spokesperson said they could not comment further while the police investigation is ongoing.
Norris was elected as the MP for North East Somerset and Hanham in 2024, defeating the Conservative MP Jacob Rees-Mogg.
The MP has also served as the Mayor of the West of England since 2021.
