Three boys have been warned about their behaviour after setting branches on fire in Cassiobury Park last night.

Police and firefighters were called just after 9.30pm on Sunday to Sheperds Road after branches were set alight in the alley between Sheperds Road and Stratford Way.

The three youths allegedly broke branches from a fallen tree to start the fire. 

Firefighters smothered the branches to extinguish the flames.
