A pervert spied on a young girl by putting his iPhone under a cubicle in female public toilets.

Dorniel Nica, a registered sex offender, had filmed the teenager in Warrington ‘s Golden Square Shopping Centre.

The 28-year-old has appeared at the town’s Magistrates’ Court in connection with the incident.

A teenage girl had been in a cubicle of the shopping centre’s public toilets on October 2 this year after feeling sick, the court was told.

The girl, whose identity is protected, said she saw a hand holding a black iPhone coming from underneath the partition with the neighbouring cubicle.

She believed the phone was recording and that there was a man in the cubicle next to her.

The girl also believed she could hear a man performing a sex act.

She and a friend then approached two Cheshire Police officers who went to the toilets but were unable to find the man.

They then scoured CCTV at the shopping centre, and saw that a man had entered the female toilets at 5.12pm and left at 5.55pm.

Officers were able to take an image of the man from the footage and submitted it through Retrospective Facial Recognition (RFR) software.

The search returned a match for Nica and he was traced to an address in Warrington.

After being arrested, Nica was later charged with voyeurism and attempting to observe a person doing a private act.

Police Constable Wendy Whitehead, officer in the case, said: ‘If it wasn’t for the bravery of the victim for approaching the first police officers she had seen we may not have been able to achieve the result we have done.

‘Thanks to the new technology available to us, we were able to identify Nica quickly and effectively, allowing us to make further enquiries and ascertain his whereabouts. This led us to get justice for Nica’s victims and put a prolific offender behind bars and off the streets of Cheshire.’

Nica, of Cherry Road, Chester, was sentenced to 36 weeks imprisonment.

He was also handed two restraining orders against two girls and ordered to pay court costs.
