Police and trading standards officers are joining forces to tackle growing concerns about under-age drinking in Bingley.

Several youngsters were arrested for being drunk during two free music events in the town this month.

And police say the problem of under-age drinking is a growing concern, with schoolchildren as young as 14 becoming involved.

Bingley Police Inspector David Drucquer said there was no evidence the youths had been drinking in the town's pubs.

He said: "We believe most of the alcohol came from off licences and licensed shops. There were lots of youths in the 14 to 17 age group at the Music at Myrtle event who had been drinking excessively."

Insp Drucquer said under-age drinkers ran the risk of being arrested for public order offences and urged parents to exercise some responsibility.

He added officers from Bingley would be joining forces with West Yorkshire Trading Standards to carry out test purchases in the area.

David Lodge, of West Yorkshire Trading Standards, said: "Under-age drinking is an ongoing problem and we receive a steady stream of complaints from the police and public.

"Test purchases are not a way of tricking anyone into selling to children - we use them to detect people who deliberately flout the law."

The concern about under-age drinking comes after a spate of five violent incidents centred on Bingley's pubs and nightclub.

Police say two Bingley men were arrested in connection with the violence and are currently on police bail pending further inquiries.

Insp Drucquer said: "More arrests are anticipated. All the incidents are separate but there is a common factor. Extra patrols put in place after the incidents are continuing and the level of violence has reduced dramatically."
