Extra police are patrolling the streets of a Leeds suburb after petrol bombs were thrown at a police patrol van.

Trouble started after anti-social behaviour notice were issued against ten teenagers in the East End Park area of the city.

No-one was injured during the disturbance and no police vehicles were damaged.

But police want to prevent a repeat of the outbreak.

West Yorkshire spokeswoman told BBC News Online the force had contingency plans in place to deal with any problems in the area.
