A DIY store owner says white van drivers and passers-by keep using his car park to have a POO - and has released video of the latest culprit.

Vaughan Colley, managing director of Building Plastics Wales, said he was regularly shocked when he made the grim discoveries.

He said on four occasions a human has defecated in his car park - including a white van man.

Vaughn eventually installed CCTV and has now caught on camera the latest suspect - a woman who was on a walk with a man.

The video footage shows the woman running into the car park with a man and then crouching down behind a hedge at around midnight on Monday, May 17 on Penmaen Industrial Estate in Pontllanfraith.

After handing her bag to the man, the woman appears to pull her trousers down to relieve herself while the man stands waiting. Once she's done, the pair casually walk off together.

Vaughan, 46, said: “It’s the fourth time this has happened.

“I don’t think it’s legal – if a dog is not allowed to do it, I definitely don’t think a human counts.”

Vaughan came into work the day after the incident and spotted the poo.
