Graffiti artist Rick Shipley has got it covered after appealing to Bradford Council to free up more walls across the city for people to express themselves legally.

Mr Shipley, 30, who has been teaching graffiti for the past seven years, said he had heard from a school and the owner of a rally car who want to give him free rein with the spray paint.

"I've heard nothing from the Council but I've had a few calls from people who want me to do some work for them but I'd still like to hear from developers and businesses who have drab shutters who would like to us come and legally express themselves," he said.

A Bradford Council spokesman said it was too early to think about introducing another wall but its officers were monitoring the ones at Odsal Top.

"If it's a success then we will consider seeing if it's feasible to have another one," she said.

The Shipley artist visits schools, youth clubs and prisons across the country as part of the business he set up called Cageone.

Last year he got together with a group of other graffiti artists from Bradford to lobby councillors for somewhere to paint legally and in November they were given the go ahead to work their art on the subways at Odsal Top - but he wants there to be more.

Mr Shipley, who has been practising graffiti since he was 18 and only paints at permitted places, said the more legal walls Bradford introduced, the less trouble the Council would have with illegal graffiti artists who cost the city around £100,000 a year.

Earlier this month a zero tolerance clampdown on graffiti was launched.

The Council and police have teamed up to offer £500 rewards to anyone who helps bring the most prolific offenders to book.

They plan to issue posters carrying the tags of the worst offenders, asking people to call in if they recognise the work.

Damian Fisher, the Council's principal waste management officer for street cleansing, believes graffiti increases the fear of crime and brings neighbourhoods down and can lead to clashes over territory. "We want to show zero tolerance towards graffiti, " he said.
