Police are hunting for the unidentified man after his call of nature in Shepherd's Bush Green, west London.
At approximately 2.40am on Sunday, a man captured on CCTV can clearly be seen with his pants around his ankles, defecating next to the brand new children’s play area.
He loitered on the green and drinking from a can before picking up what appears to be a used tissue from a picnic table and walking to the play area.
After the incident he walked away from the scene, directly into the beam of a night vision camera.
The man is approximately 40 years old, of medium build with a bald head. He was wearing blue denim jeans and a grey hooded top with a white logo.
Hammersmith & Fulham Council are appealing for anyone who knows the man to get in touch.
