A teenager used his mobile phone to secretly film young girls changing at a swimming pool.

The 16-year-old used his mobile phone to covertly record footage of two ten-year-old girls while they were drying off and getting changed in a cubicle at Perth Leisure Pool.

The teenager, who cannot be named for legal reasons, was placed on the sex offenders register and under social work supervision for a year at Perth Sheriff Court on Wednesday.

He admitted using his phone to record video of the girls while they changed in a private cubicle at the pool on 11 June this year.

Sheriff Gillian Wade told him: "Clearly this has left you with a conviction for a sexual offence on your record, which will remain with you for the rest of your life.

"It is important your offending behaviour is addressed to prevent any re-occurrence and to provide protection for the public in the long-term."

She also imposed a conduct requirement which means social workers and police can search any internet-enabled device he owns at any time.
