Police in an Essex city received an "unprecedented number" of reports last night of teenagers firing fireworks and causing "mindless damage" during Halloween chaos.

Officers in Chelmsford responded to calls regarding teenagers being in possession of and blasting fireworks at members of the public.

Residents also reported the youngsters were committing "mindless damage" to property by throwing items at cars and houses.

Police say dog walkers and families with young children were targeted yesterday evening by "senseless anti-social behaviour".

Essex Police issued six dispersal orders during Halloween in Southend, Rayleigh, Frinton, Theydon Bois, Canvey and Benflet.

The force was also given additional stop and search powers in Basildon after receiving information there may be disorder involving weapons in the Laindon and Pitsea areas.

An Essex Police spokesman in Chelmsford said: "Tonight we have dealt with an unprecedented number of calls regarding teenagers being in possession of and firing fireworks at members of the public and committing mindless damage to property by throwing eggs and other items at cars and houses.

"Dog walkers and other families that were trying to enjoy Halloween with their young children have been targeted this evening by senseless anti-social behaviour.

"Our message and plea to the parents of all children within the district is to have that conversation about how dangerous fireworks can be and the potential injuries that they can cause when not handled or used correctly and about ensuring their behaviour whilst out is safe and respectful.

"We would also urge all parents to know where their children are, what they plan to do whilst out and make sure they are asked to come home at a reasonable time in the evening.

"We have returned a number of children home tonight to unhappy parents and we rely on you, the public to help us keep everyone within the district safe."
