Teenage off-road bikes are "putting families in danger" after an incident where they allegedly accelerated towards a young boy.

Groups of scrambler bikes have been reported circling residents and damaging football pitches in Sully.

Concerns have been raised after bikers allegedly accelerated towards a five-year-old boy and his mother while on the beach in the Vale of Glamorgan.

Sully resident Lisa Desmond said she was walking on the beach behind Sully Primary School with son Joe when the incident took place.

The mother-of-one said: “We were on the beach and I heard engines – at first I thought they were jet skis. I looked up and could see them coming along the coastal path.

“As I went up to see what was happening one of the boys had gone to the beach was travelling towards Joe.

“I just screamed at the rider and he turned slightly and went towards the field.”

She added: “Joe was beside himself screaming and crying as they’re really loud.

“It took me a while to calm down I was absolutely livid. We were there with another family as well and one of the riders ran over one of the boys’ feet.”

The incident follows previous damage to youth football pitches overlooking the beach.

Lisa added: “It’s dangerous – they are in the middle of the road doing wheelies.

“The pavements in Sully are quite narrow – it only takes one small thing and someone will be killed. They’re not supposed to be on the road – they’re not licensed.

“If this is the winter I don’t want to think what it will be like in the summer.”

Sully community councillor Phil Baguley said a group of off-road bikers have been congregating on Friday nights for the last six months.

The independent councillor said: “They have been causing havoc.

“The keep going across the football pitch and the kids can’t play on it. There are big gouges on it – we get it ready and they do it again.”

Coun Baguley said residents have been urged to report incidents to South Wales Police.

He said: “It’s only a matter of time before someone is hurt.”

Sully resident Steven Oaten said: “It impacts on the local football teams who need to use the pitches after they have been churned up – especially the one at the rear of Sully school that still bears the scars.”

Rod Thomas, chairman of Sully community council, said: “These bikes have no plates and the drive down the middle of the road and push cars off it.

“We have called the police numerous times.

“There were roadworks on South Road and I was in traffic and they went up the road pushing cars onto the pavement.

“They come down here to race on the beach. There is no care.”

South Wales Police have been contacted for comment.
