A teenager was sexually assaulted at T in the Park by a member of the official security staff.

The 17-year-old woman sought help after becoming detached from her friends but a court heard security officer Allan Freedman exploited her vulnerable state to kiss and grope her.

The 43-year-old had his name added to the sex offenders register after he admitted carrying out a sexual attack on the girl.

Freedman's attack was one of a number of incidents recorded at the music festival as serious and sexual assaults reached record levels during the 2015 event.

Fiscal depute Carol Whyte told Perth Sheriff Court the girl became separated from her friends at the festival on July 10.

The girl thought they would be in the Slam tent so she found a member of staff, Freedman, and asked him for directions on how to get there.

Ms Whyte told the court it was clear from the fact Freedman was wearing a high-visibility vest that he was part of the official security team for the festival at Strathallan Estate.

She said Freedman led her towards the tent she was looking for before stopping and groping her as well as kissing her repeatedly on the face and lips.

Ms Whyte said the girl, who cannot be identified for legal reasons, was "terrified" as a result of Freedman's behaviour and the police were called in.

Freedman, of Capelrig Street, Thornliebank, Glasgow, admitted sexually assaulting the girl by handling her knee and waist and repeatedly kissing her without consent.

He no longer works for the security contractor who employed him to work at the festival, the court heard. Sentence was deferred for reports.

T in the Park recorded the most serious assaults in its history last year but overall crime at the festival dropped, a police report revealed. There were six serious assaults at the 2015 event compared to one in each of the festival's previous three years.

Chief superintendent Eddie Smith's report said petty assaults rose from 15 to 36 and there were 11 crimes of threatening behaviour.
