A dog walker said she tried to humiliate a man who was masturbating in a park bush after he asked her to perform a sex act on him.

The woman, 43, spotted the man masturbating in Blake Recreation Ground in West Wickham at around 7.30pm last night.

"After a few laughs at him and a few f offs I told him I would have more fun sucking an ice lolly as his was clearly tiny," the dog walker told News Shopper.

She added: "I wanted to make him feel stupid and humiliated as he clearly wanted to make me distressed.

"He only left when I got my phone to dial 999."

The woman, who didn’t want to be named, said she "wasn’t shaken up" by the unexpected incident.

She said the man was masturbating as she sat on a bench near the basketball court.

According to the witness, she "verbally intimidated" the man who eventually ran off towards the junction of Ravenswood Crescent and Pine Avenue.

He is described as white, aged mid to late 20s, with dark hair and was wearing black shorts and a red t-shirt.

A police spokesman said: "We were called to Blakes Park, West Wickham after a woman reported that a man had exposed himself to her.

"Officers attended and searched the park, but the man was not found. Enquiries are ongoing."
