A UNIVERSITY employee has been arrested after a sawn-off shotgun and £100,000 worth of cocaine and heroin were discovered on campus.

Students told of their shock after police raided a building at the University of Teesside, in Middlesbrough, on Monday night and found one of their biggest ever hauls of crack cocaine and £30,000 in cash.

Yesterday morning, they arrested a 45-year-old Middlesbrough man on his way to work at the university.

Police raided an outbuilding, which is part of the former library, after they were tipped off by security staff. A spokesman said they planned more raids at university sites.

Detective Sergeant Paul Templeton, of Middlesbrough drugs squad, said the cocaine and heroin was enough to supply Middlesbrough's drugs market for a week.

A 25-year-old psychology student from Redcar, east Cleveland, who asked not to be named, said: "It is a bit scary."

Det Sgt Templeton, said: "We are pleased with this recovery and it paints a real picture of what is floating around Middlesbrough at any given time.

"These are some of the biggest chunks of crack I have seen. Some of them would fetch £500 on the street."

Last night, the man arrested was still being interviewed by police.

A university spokesman said: "Teesside University has a strict anti-drugs policy and we have co-operated very closely with Cleveland Police in their inquiries leading up to this arrest."

He confirmed that the staff member arrested had been suspended in line with normal procedures.
