Sex Assault Squad Detectives are currently searching for two men they believe to be responsible for an indecent assault in Secret Harbour on Thursday.
According to police, a 30-year-old woman reported being assaulted by two men in the parkland within La Palma Square at about 6.10pm last night.
The woman reported the two men blocking her path as she walked along the alleyway between Carmague Green and Sicily Green.
The men forced her to the ground and indecently assaulted her in the bushes alongside the alleyway.
They then ran off when they heard someone approaching them on the path.
One man was described as being in his thirties, fair skinned, approximately 190cms tall with a slim build, scruffy blonde hair and blue eyes. He was wearing a white t-shirt with a blue pattern.
The second man is described as being in his thirties, dark skinned, approximately 165cms tall with a solid build, dark brown curly shoulder length hair and some facial hair. He was wearing a black t-shirt, knee-length denim shorts and black thong-type shoes with a Velcro strap.
Mandurah detectives would like to speak to anyone who was in the vicinity of the incident between 6pm and 7pm who may have seen the men.
Anyone with information is urged to call Crime Stoppers on 1800 333 000, or report the information online at crimestopperswa.com.au.
