They warn off-road biking is a growing problem around Mansfield's Oak Tree Lane Estate and parts of Forest Town.

Police say most riders do not realise the law when riding without insurance, licence or helmet, or on private land.

Police Community Support Officer Ian Wright was called out six times in one night to bikers racing around residential areas and playgrounds.

'Bikes seized'

He said: "Riding motorbikes without insurance, and safety helmets, in a careless manner around housing estates and on common land is not only an offence but also has a major impact of peoples' lives.

"Local residents report noise late at night and also more recently a new �20,000 golfing green was being used for biking activities.

"Most reports state juveniles between the ages of 12 to 17 are riding these motorbikes and can clearly not understand the danger of what they are doing."

He urged parents and guardians to be vigilant of the "consequences."

He warned those using a motorcycle off-road will be reported and may face prosecution.

If the initial reprimand is ignored the rider risks having the bike seized under Section 59 of the Police Reform Act.
