Revellers at Brighton's Pride festival have been accused of leaving a park covered in urine.

One park user is so incensed he has cordoned off a section of Preston Park after witnessing it being used as a toilet at the weekend.

Nick Benn, 47, left signs on trees running inside the park, parallel to Preston Park Avenue, reading: "Warning! These trees were used as a toilet by thousands of people and are unsafe for children to play in."

He wound tape around trees to alert people to what he said was a health and safety risk.

Mr Benn, of Larkfield Way, Brighton, said: "It is just horrific. It stinks of urine and worse.

"There is mess and toilet paper everywhere. Children play here and run in and around these trees. I am worried about their safety.

"Nothing was being done about it and I felt I had to take action myself to protect people."

By mid-afternoon last Saturday, the park was filled with 120,000 people and queues for the toilets stretched up to 50m.

Mr Benn said inadequate facilities forced hundreds of desperate people to resort to using the bushes.

One mother contacted The Argus to complain about broken glass still littering the field yesterday and flyers advertising fetish wear that had been seen by youngsters.

Pride operations manager PJ Aldred said the clean-up would take time and asked residents and park users to be patient.

The section Mr Benn was concerned about was cleaned up within half an hour of The Argus contacting Ms Aldred to alert her to the situation.

Ms Aldred said the £25,000 clean-up operation was running 12 hours ahead of schedule and was due to finish by 6pm yesterday.

She said: "We have been clear the park wasn't going to be clear straight away.

"All we could do was reiterate this and ask people to bear with us and stay away from the park until the operation was complete.

"It takes a couple of days to clear Preston Park after any large event and we are now the biggest. The clean-up happens as fast as it possibly can.

"We are thrilled with the speed of the operation this year. To finish ahead of schedule on such a major job is superb."

There were more than 200 toilets and urinals, a 46 per cent increase on last year.

Ms Aldred said: "We will be increasing facilities again next year, to cope with the crowds."
