FOUR men wearing masks and gloves broke into a house in Cricklewood and sexually assaulted a teenage girl.
The 19-year-old woke up shortly before 5am to find one man pinning her down while three others searched her room.
Cash and other valuables were stolen from the property in Oxgate Lane during the raid, on October 24.
The intruders ran off towards Coles Green Road. It is thought they had tampered with the letterbox to break in.
One of them is described as black, with a moustache.
