The Brentford home of MPs Alan and Ann Keen is today a crime scene while police investigate an alleged sex attack.

Two weeks ago a group of 10 squatters moved into the home and were yesterday ordered to leave by a judge - it is believed the group decided to hold a final party.

A Met Police spokesman confirmed the Keens' home was sealed off as a crime scene after a report was made to them about an alleged sexual assault last night.

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.

The squatters are helping the police with their enquiries.

Yesterday Mr Keen said he was "delighted" the group were leaving his home.

Speaking today Mr Keen said: "This just goes to prove we were right all along, these people were up to no good in our house.

"We are obviously very distressed and this has made a bad situation worse."

The MP said he had been called by police this morning who told him they had taken over the house and will be doing scene of crime tests until tomorrow.

No one has been arrested.
