Savanagh Healey, above, needed hospital treatment after she was hit while crossing Burnhall Drive, close to Seaham School of Technology.

The 13-year-old suffered a bump to her head, cuts, grazes and damage to her foot.

Savanagh, who needed almost a week off school as she recovered from the accident at home in Ryhope, said: "I was just shocked for about four hours afterwards, and was still crying and trying to remember what happened.

"My foot was really hurting and my head has been sore."

Now police say they are determined to take a tough stand against rogue riders and poor parking which has caused havoc outside Seaham School's gates.

Officers and staff at the school were already working together to ward off troublemakers riding near its grounds.

A 16-year-old boy, who has no links to the school, was traced to an address in Deneside a short time after the incident.

He has been reported for driving offences and questioned, with a decision about charges yet to be made.

The incident was witnessed by pupils and Police Community Support Officers, who were on patrol after reports of bikes being used antisocially in the area earlier in the day.

Efforts are being stepped up to deal with rogue bikers, with extra signs put up and inquiries made into extending guardrails and keep clear markings.

A letter is also being sent to parents urging them not to park indiscriminately, which is also said to be causing a danger.

Savanagh said: "I'm pleased something is being done about it because I don't want other people to be hurt."

Her mum Lisa, 36, whose son Billyray, 16, and daughter Marney, 11, are pupils at Seaham School, said: "Before this happened it was bedlam outside the school, not just because of scooters but cars.

"Since then it seems to have been better. Savanagh's recovering, but she's still got aches and pains and cuts."

Beat bobbie Pc Janet Hutchinson said patrols had been increased in the area. She added: "This issue was highlighted through our Police and Communities Together meetings and through the school's headmaster."

Headteacher David Sheild said: "The issue concerns me hugely and it's putting the pupils' welfare at risk."
