Sussex Police released images of a vulgar man who was captured on CCTV pulling his trousers down and pooing against a taxi office door and wall.
The footage of the incident outside the GM taxi office in Lewes took place at approximately 2.15am on Sunday April 7, and the police hope to bring the perpetrator to justice.
Officers called the offender a "poorly-mannered individual".
Footage shows the man initially standing outside the office, before cutting to him taking his trousers down and squatting.
He can then be seen defecating against the door and window of the cab office, before pulling up his trousers and appearing to smile before turning to admire his work.
In the appeal, police ask if anyone recognises this "proud individual". If you know the culprit please contact Sussex Police via its website here, quoting serial 1205 of 07/04.
