Police have been urged to fine teenagers who ride mini bikes on Birmingham pavements by a Government Minister.
Home Office Minister Andy Burnham called on Paul Scott-Lee, the Chief Constable of West Midlands Police, to clamp down on youngsters causing a menace.
The vehicles, sometimes known as micro-bikes, can reach up to 40mph, although many parents buy them as toys.
Teenagers have been seen driving the bikes in public parks, on the pavement, and on the road, even though this is illegal unless they are taxed and insured.
Erdington MP SiUn Simon (Lab) complained officers had been ordered not to chase mini-bike riders in case someone was injured.
Speaking in the House of Commons, he referred to teenagers who had received Anti-social behaviour orders, who he called "asboids".
He said: "The rumour in the West Midlands is that a 14-year-old asboid on a mini bike is difficult and dangerous to catch and that the police have been told not to chase them, lest the charming asboid or, indeed, the policeman should be injured.
"What advice can the Home Office offer the police, because if we cannot catch those involved, we cannot confiscate their mini bikes or do anything about the problem?"
Mr Burnham said: "The inappropriate use of mini bikes is a growing problem and incidents that disturb local residents, damage the environment, and put the safety of the public at risk are becoming more frequent."
