Police are hunting a pervert who has sexually assaulted young women in a series of morning attacks in Aylesbury town centre.
Incidents started on April 16 with the last reported assault on April 20 and police believe they are linked.
The first incident happened on April 16 at 8.40am in the lift of the bus station waiting area of Friars Square, where an Asian man in his late teens approached a woman in her twenties and tried to grope and kiss her.
She pushed him away and was able to get to safety.
The second incident, between 8.15am and 8.40am on April 17, happened in the same bus station on stairs leading to Friars Square and also involved the man approaching his victim, another woman in her twenties, and attempting to grope and kiss her.
She managed to struggle away from the man and left the scene.
The third incident, between 8.15am and 8.40am on April 20, occurred at the cash machine outside Natwest bank in Market Square.
This time, the victim either fell or was pushed over and the offender climbed on top of her while making inappropriate sexual comments.
In this instance, the offender fled the scene when a passer-by approached him.
The man police are searching for is Asian, aged in his late teens, around 5ft 6ins, of medium build with short dark hair.
In the first two assaults he was wearing black shorts with a white T-shirt and carrying a sports bag on wheels with black writing on it.
In the third assault, he was wearing dark trousers and a white shirt.
All three victims were women in their early twenties, but police said they look younger.
