A former Mandurah police sergeant will be sentenced later this year after he pleaded guilty to five child sex offences.

Andrew James Maher, 42, was charged with two counts of exposing a child under 13 years of age to indecent matter, and three counts of using electronic communication with intent to expose a person under 16 years of age to indecent matter.

The offences were committed on October 2 and 3, 2017, and he was arrested after an investigation by the Child Abuse Squad.

He appeared in the Perth District Court last Friday and pleaded guilty to all charges.

Six other charges were discontinued.

Maher is due to reappear in the Perth District Court for a sentence mention on May 31.
