A NAKED man indecently exposed himself to a school pupil in Lydiard Park.

Children at nearby Lydiard Park Academy have been warned to remain alert after a man was seen with no clothes on at approximately 4.30pm on September 12.

The principal of Lydiard Park Academy, Gary Pearson, told pupils to be vigilant when walking home after school and encouraged them to walk with friends.

Mr Pearson said if pupils are approached they should ring the police or return to school if they are close enough so the staff can ensure pupils get home safely.

There will also be a police presence at the school.

Police say enquiries are ongoing and anyone with information is encouraged to phone 101.
