An aide to Kent MP Craig Mackinlay has been arrested on suspicion of raping a woman in Parliament.

Police are reported to have stormed the offices of the South Thanet MP as part of the police investigation into Sam Armstrong.

The staff member is alleged to have attacked a woman in an office building after a drinking session on the House of Lords' terrace.

Police have confirmed a 23-year-old man was arrested in the early hours of Friday.

Former Medway councillor Mr Mackinlay's office was raided by six uniformed officers on Friday and the area was sealed off as a crime scene.

Mr Armstrong has been bailed until January while police continue their inquiries.

A spokesman for Mr Macklinlay's office said: "Mr Mackinlay was made aware of an allegation against a staff member and granted permission for the police to access his Westminster office.

"Mr Mackinlay is monitoring the situation and awaits further details from the police and Parliamentary Authorities."
