An e-fit of a man wanted in connection with three sexual assaults has been released by police in Buckinghamshire
The first assault happened on the 6 November and the other two took place three days later and all were in the Wolverton area of Milton Keynes.
Thames Valley Police believe the man is local to that area and said officers were looking for a young Asian man between 16 and 18 years old.
Police are linking the attacks and have appealed for the public's help.
The first attack happened on 6 November at about 1430 GMT when a 48-year-old woman got off the number 5A bus in Stacey Bushes and started walking along the Redway towards Hodge Lea.
The offender, who was also on the bus, approached her from behind and assaulted her before running off through an underpass towards Wolverton.
Three days later, on 9 November, a 43-year-old woman, was walking in Gloucester Road, Wolverton at 1740 GMT when a man walking towards her, grabbed her and sexually assaulted her.
Twenty minutes later a 23-year-old woman was sexually assaulted in Cambridge Street, Wolverton.
Det Sgt Jeffrey Capstick said: "We believe these offences are linked and in each case the offender has touched the victim inappropriately before running off.
"Because the offences have all taken place in Wolverton, we believe the offender is local and hopefully someone will be able to identify him from the e-fit."
