A student nurse who tried to bite staff in the medical tent during a drink-fuelled rage at T in the Park was fined £750 yesterday.

Londoner Harriet Dodd, who had to be pinned down by a doctor and security staff, shouted anti-Scottish abuse at police officers. She was also ordered to pay £100 compensation to security guard Andrew McNeil after trying to bite his arm.

Dodd's behaviour was criticised by Sheriff Lindsay Foulis, who said: "If you actually become a nurse I hope you don't have to come up against anyone exhibiting the behaviour you did."

Dodd, 20, from London, turned up at the medical tent on July 12 with her sister looking for treatment, but she immediately began lashing out at staff.

Fiscal depute Janine Bates told Perth Sheriff Court: "She was heavily under the influence of alcohol and/or drugs. Her behaviour was erratic and unpredictable. She became aggressive towards medical staff, and assistance was summoned from security personnel. She resisted efforts to apply a bandage and Mr McNeil tried to assist by taking hold of her arm.

"She partially broke free, whereupon she lunged forward with her mouth open and her teeth bared towards his right arm. Her teeth made contact with him but he managed to withdraw his arm before she could pierce the skin. The doctor assisted in restraining her."

Police officers arrived at the tent and Dodd shouted anti-Scottish abuse.

She asked the police to telephone her mother and when they said she would have to wait until she got to the police station she again flew into a rage. Ms Bates told the court that Dodd kept the abuse during the 40-mile trip to Dundee and she was held in custody for two nights.

Solicitor Mike Tavendale, defending, said: "She has little or no recollection of what happened."

Dodd admitted assaulting Mr McNeil in the medical tent on July 12. She also admitted making racist remarks and breaching the peace by acting in a disorderly manner.
