Police confirmed they are still investigating an alleged sex attack at the Brentford home of MPs Alan and Ann Keen.

Officers sealed off the home when a homeless woman claimed she had been sexually assaulted as a group of squatters held a leaving party after being kicked out of the couple’s home in July.

A Metropolitan Police spokesman said officers expected DNA results within a week and the investigation was still active.

This week the couple’s home remained boarded up despite Mr Keen, MP for Feltham and Heston, saying the couple wanted to get building work started on the property as soon as possible.

He blamed legal problems for the delay.

A source told the Hounslow and Brentford Times the party was gatecrashed by “a large gang” who have caused “thousands of pounds” worth of damage to the Keens’ “main” residence.
