FED-UP bosses claim arsonists and fly-tippers are harming their businesses.
Businessmen on the Park View Industrial Estate, off Brenda Road, in Hartlepool, have appealed for intervention after becoming increasingly sick and tired of deliberate fires being set and rubbish being dumped around the nearby land.
In the past year, the side of a building has been set alight and various skips and industrial bins have been torched.
There is also rubbish, including mattresses, tyres and household waste strewn all over various areas of grassland around the site.
In 2012, Cleveland Fire Brigade were called to attend five fires on the land and six the year before.
But a security boss on the site says they have many more fire incidents which staff have put out themselves.
Businesses on the estate, which has 50 units, believe the problems have got worse in the past year.
The latest incident was on Tuesday night when a skip was set on fire.
And over the weekend, an industrial container was dragged from outside one of the units and set alight on a field.
Tony Young, managing director of Blindcraft at the site, said: “In the past six months it has been really bad. “It seems nobody can do anything for us.”
Michael Rooney, proprietor of the nearby Eurotread garage, said: “I’m gutted that they keep coming around here and making all this mess.”
Kevin Smith, of Park View Site Security, who has looked after security on the site for 13 years, said he had received verbal abuse when approaching youths who had been seen hanging around.
“We are just being neglected.”
A council spokesman said: “The industrial estate is privately owned and managed.
“However, as it has done in the past, the council would be happy to work with the landlord, tenants, the police and the fire brigade to tackle the issues raised by some of the tenants.”
Newcastle-based Knight Frank, which manages the land on behalf of owners UK Land Estates, would not comment.
Sergeant Mark Haworth, of Hartlepool Police, said police have increased patrols in response to anti-social behaviour concerns in the area.
He added: “There is a multi-agency approach to tackling these issues.”
and we would ask the public to continue to provide us with information and alert us when they observe anti-social behaviour in the area by contacting us on 101.”
He said a police community support officer is dedicated to any issues involving tethered and loose horses in the area, who works closely with the RSPCA, and urged anyone who comes across horses found to be neglected or ill-treated to contact PCSO Kirsten Anderson or PC Mike Pilbeam, joint equine officer, on 101.
