A man in a pink top exposed himself to two women in a park in Bicester.
The man in his thirties approached two women aged 18 and 21 in Bure Park Nature Reserve and exposed himself at about 7.30pm on Sunday.
He then left using the main pathway through the reserve.
The man was wearing a luminous pink polo top which featured a black and white horizontal line across the chest.
He was also wearing tan-coloured shoes and was about 5ft 6ins to 5ft 8ins tall, with brown receding hair and stubble.
