Police will take to the streets on Halloween armed with head cams to record any anti-social behaviour.

The announcement comes just days after Wiltshire Police confirmed they were stepping up patrols across North Wiltshire on Halloween in a bid to tackle anti-social behaviour.

Inspector Gavin williams, of Chippenham Police, has issued a warning to potential troublemakers claiming if you are going to engage in disorderly behaviour on Halloween you are going to get filmed doing it.

Special cameras will be attached to the helmets of half a dozen police officers tasked with patrolling the streets of Chippenham, Calne and Corsham on Wednesday night.

Insp Williams said: "We hope they will act as a deterrent as well as an excellent evidence gathering tool.

"It assists us because people don't like being recorded on camera so they don't play up. And if they do commit any offences then the cameras give us excellent evidence which can be used in court."

He said Chippenham police had used the cameras several times before when patrolling the town centre on an evening or at the weekend.

He added: "We are looking to increase the use of them and make people aware that we are doing so."

Posters will be put up in the run up to Halloween to let people know that police officers will be using these cameras on Halloween.

These posters read: "Warning, police using Head Cameras in this area.' It is followed by the slogan 'prevent, deter, catch, convict.'"

Meanwhile, shops and supermarkets are refusing to sell items such as eggs and flour to children and teenagers in a bid to tackle troublesome trick or treaters.

A spokesman for Wiltshire Police said: "Halloween can be harmless fun, but occasionally, members of the community, particularly the elderly, can become distressed with unexpected callers.

"The behaviour of some trick-or-treaters can also be intimidating and even criminal, with examples in previous years of anti-social behaviour, criminal damage to property and graffiti."

Insp Williams said: "We will have more officers patrolling on Halloween in Chippenham, Calne and Corsham to deal with anti-social behaviour. Anyone found acting in an anti-social manner will be taken home.

"We have the power to ask people to leave a certain area and if they fail to do so they run the risk of being arrested.

Anxious residents are being invited to download posters from the Wiltshire Police website which read: "Happy Halloween, sorry no trick or treat here please." They are also available from libraries and Tourist Information Centres.

It is hoped that these posters will act as a deterrent to youngsters wanting to knock on doors to homes where they are not welcome.

Halloween celebrations in Calne will kick off with a funfair in the towns Market Place car park.

In an attempt to get families back into the town North Wilts District Council have agreed to waive all parking charges in Church Street.

Last year 90 young people ran rampage in the town smashing windows, lighting fires and throwing eggs making national news.

By encouraging families into the town organisers hope to avoid a repeat riot.

Lead member for parking at North Wiltshire District Council Cllr Chuck berry said: "We are more than happy to waive parking charges for the Church Street car park on Halloween.

"Halloween is celebrated by many families and this should provide an attraction for the whole family to enjoy and should prevent a repeat of anti social behaviour on Halloween night in the town.

Calne Police will be putting more officers on the street on both Tuesday and Wedsnesday evenings.

PC Alan Blake of Calne Police said: "We want to reassure members of the public we are stepping up patrols around the town.

"People will be able to enjoy themselves without being afraid of anti social behaviour.

"Last year some members of the public were quite scared by behaviour and we want to avoid that this year."

Devizes police are taking measures to reduce anti-social behaviour at Halloween by inviting young people to a disco at the Corn Exchange.

Inspector Dean Knight said police officers will be out and about around the town that night but sales of possible missiles have been thwarted.

He said: "We have an informal arrangement between ourselves and the stores not to sell flour and eggs to under 18s that day. It cannot be enforced, however."
