SHOCKING video footage captured the moment a woman was deliberately sprayed with dirt by an off-road motorbike in the Lickey Hills, after she asked the rider to stay away from her dog.

The video, which was posted by community website B31 Voices, shows at least 20 motorbikes gathering at the top of Beacon Hill on Sunday.

When two of the riders approach the woman, she asks them to 'get off your bike please next to my dogs'. One of the riders can then be heard revving their engine next to the woman.

The second biker then asks the woman to 'take the camera off us', before the other rider aims his back wheel at the woman, spraying her with mud.

A spokesman for Hagley and Rubery Safer Neighbourhood Team said: "A number of young people have been reported for Anti-social behaviour at the Beacon at the Lickey Hills.

"If this behaviour continues, it won't be long before someone is injured or worse.

"If you are the parent of one of these youths we ask you to consider your child's safety and help stop this dangerous riding."

They added: "It is illegal to ride any motorbike in public open spaces such as parks, play areas and on pavements.

"This can result in prosecution for the rider and in some cases the parents, who are held accountable for the actions of their children."
