A teenager who secretly filmed girls in a swimming pool's changing rooms has been spared jail.

Thomas Kennedy-Dack, 19, formerly of Cross Road, Gorleston, filmed four girls as they undressed in cubicles at the Cherry Tree Holiday Park in Burgh Castle, where he was working as a lifeguard, a court has heard.

All four incidents happened between February and April, with the final one on April 10, when a 15-year-old schoolgirl noticed a flash from underneath the cubicle door.

Great Yarmouth Magistrates heard today that on realising he had been caught, Kennedy-Dack fled from the changing room, hastily deleting the footage from his phone. However the victim reported the incident to staff, identifying him by his grey trainers.

He was immediately suspended by the holiday park while police carried out investigations, and he took up the option to offer his resignation.

When police searched his phone, footage of the victim could not be recovered, however three other identical videos were found, all featuring girls estimated to be aged between 14 and 17.

Kennedy-Dack who had pleaded guilty to all four counts of voyeurism at an earlier hearing was placed on the Sexual Offenders Register, where he will remain for seven years.

Addressing Kennedy-Dack in court, his victim read out an impact statement which said: 'I feel like things have changed for me. I cry every day, I cannot concentrate and this has put me behind in my GCSE studies.

'I feel sadness and despair and since your disgusting actions my confidence has been deeply damaged. When you look back to the point of realising you have ruined your life, realise that you have ruined mine too.'

Her father added that Kennedy-Dack had caused her to lose 'trust in adults'.

James Hartley, mitigating, said: 'He is deeply ashamed. He vows he will not offend again and apologises for his actions.'

Chairman of the bench, Christopher Bowles, in sentencing Kennedy-Dack to a 14-week jail sentence, suspended for 18 months, said: 'You were in a position of trust and the actions you decided to do can be considered to have been done in a place of safety for the victims, who were young and vulnerable.

'A great thing for you to take on board is the fact your victim has not asked for any compensation, as it would have been awarded in a reasonable amount. For this young lady's courage we are astounded.'

He was ordered to pay a £115 surcharge, £85 in court costs and must also complete 150 hours of unpaid work.
