A 16-YEAR-OLD boy was arrested on suspicion of breach of the peace following the ejection of 135 Caldicot pupils from their prom at Chepstow Racecourse.

Caldicot School's Year 11 prom was held at the racecourse on Wednesday and was due to finish at 12am but all the pupils were ejected at 10.30pm due to the misbehaviour of a group of pupils. It is alleged that a small group of pupils were trying to smuggle in drink, and were threatening towards staff.

Chepstow Racecourse says in future such events will have to be attended by teachers or parents.

Chief executive Phil Bell says he had no option but to close the party down.

A Gwent Police spokeswoman said they were called to the racecourse at 10.15pm due to disturbance outside the venue after the prom had been closed down. A 16-year-old boy was arrested on suspicion of breach of the peace and was taken home by officers.

They said no further action will be taken against the 16-year-old boy. Four people also received anti social behaviour referrals and had letters sent to parents as well.

Parents have previously voiced their anger that all the pupils were ejected from the prom which cost £35.

Phil Bell, executive director at Chepstow Racecourse, said they were verbally assured that parents would be in attendance.

He said: "In future any proms who want to use our venue will have in the terms and conditions which will be changed to ensure teachers or parents are present and if they are not there at the agreed time the event wouldn't go ahead. You can't expect our staff to be put in that sort of risk again."

He said it is their policy for door staff to check bags and nine hip flasks were confiscated.

A statement from Caldicot School said: "Caldicot School has confirmed that the school does not have any involvement in private functions organised by parents for pupils who come to the end of their Key Stage 4 and their GCSE courses.

The school holds its Leavers’ Day for Year 11 in June and the behaviour of pupils on that day was excellent and responsible."
