STAFF at a York library have employed a security guard to protect them from a gang of teenage yobs.

Workers at Tang Hall library asked council chiefs for the measure after they were harassed by youths during the early evenings.

Police have confirmed that the library, which was only refurbished last year, has been attacked four times in only eight weeks by vandals.

The "nuisance youths" have broken windows, vandalised and damaged property at the Fifth Avenue building.

A security guard is employed at York Central Library, but it is rare for branches to have to resort to the same methods.

But following one occasion where a group of youths had gathered in the car park while staff were trying to close up, a security guard was requested to help frightened workers finish the job.

Now a community ranger firm, run by Mayfair Security, regularly includes the library in its patrols of York streets.

An anonymous caller telephoned the Evening Press, claiming the library was "under siege" by teenage thugs.

Annie Mauger, head of libraries and heritage at City of York Council, which owns the library, confirmed that the youths were causing a problem, but pointed out that there had been no incidents for a couple of weeks.

Sgt Colin Ventress, of York Police, confirmed the force had recorded four incidences of attacks since February 1.

Ms Mauger said: "Staff weren't feeling safe leaving the building at night. The youths were causing a level of harassment and aggression.

"I find it very sad that this kind of thing happens. Of course our priority is the safety of our staff and customers.

"Broken windows cost the council a lot of money and the guards save a potential massive expense.

"It is cheaper to pay for this than replace the windows. It is safe for people to come to the library. It was basically just a few youths causing a bit of trouble.

"It is annoying, but this a group which is moving on."

A City of York Council spokesman said: "These are community facilities and when they are damaged everyone suffers.

"We would appeal to people to come forward with any information. We will then prosecute."
