The council spends over �100,000 a year removing graffiti

"Street Level" features three convicted offenders whose joint tagging activites amounted to more than �1m of criminal damage in the city.

The film, which is being sent to all secondary schools, also shows teenagers how to take part in legal street art.

A Facebook group has been set up for people to log on and post their views.

"Graffiti-versus-art is a subject long and hotly debated in Bristol, due partly to its links with Banksy and other home-grown graffiti artists," said Bristol City Councillor Judith Price.

Legal graffiti

"Unfortunately young people can be particularly susceptible to becoming involved in illegal graffiti and tagging," she said. Bristol City Council currently spends over �100,000 per year removing graffiti.

The council has recently set up a legal wall in Riverside Park as well as establishing street art projects such as Happy Lane and Trenchard Street.
