A 16-year-old girl was sexually assaulted by a man as she walked down an alleyway in Oxfordshire.
The teenager was walking along the alley in Noble Road in Henley-upon-Thames when the man approached her.
He said he was doing decorating work at Gillotts School and asked her for directions before grabbing her inappropriately.
He fled the scene on Monday and the girl later reported the incident to Thames Valley Police.
The attacker is described as 5ft 8in tall, with dark hair and yellow, crooked teeth.
He is about 40-years-old and was wearing brown three-quarter length shorts and a blue jumper with white paint stains on it.
