Police searching for suspect after child sexually assaulted at Perth indoor play centre

Police want to speak with anyone who was at a children's activity centre in the northern Perth suburb of Balcatta on the weekend after a sexual assault against a child was reported.

They say the child was sexually assaulted by a male at The Beach House Kid's Fun Centre on Halley Road on Saturday between 1.30pm and 3.30pm.

"During his visit to the centre he was sexually assaulted by a male," a police spokeswoman told WA Today.

Anyone who has information is urged to contact police.
