At approximately 5pm on Saturday (November 1) a woman was walking along New Street when a man approached her from behind. He grabbed her between her legs and walked off.

Minutes later on the crossing by the Britannia pub the man assaulted the woman a second time by again grabbing her between the legs. He then ran off towards Buckingham Road.

The woman continued to walk along Buckingham Road when she saw the man again and phoned the police. She made her way back to the Britannia pub and saw the man walk past the pub in the direction of Aylesbury town centre.

The man is Asian, around 25-years-old and was wearing dark trousers, a blue jacket with red sleeves and a dark woolly hat.
