Man arrested over alleged rape inside UK parliament

Armstrong, 23, who is a chief of staff to Tory MP Craig Mackinlay  has been arrested on suspicion of rape following an alleged incident inside Britain's Houses of Parliament, London police said on Tuesday.

Police visited the MP’s office the following morning, sealed it off as a crime scene, and arrested the suspect.

Kent MP Craig Mackinlay said police visited his office after he was told of an allegation against a staff member on Friday.

The attack reportedly took place in the early hours of last Friday and the suspect, who police have not named, was detained later that day. Police said he was not a lawmaker.

Police said the man had been released on bail until January pending further inquiries.

A spokesman for the House of Commons, one of Britain's most recognisable buildings on the banks of the River Thames in Westminster, said they were aware of the incident and parliament was working closely with police.
