A 20-year-old man who allegedly asked a teenager to perform sexual acts outside a Duncraig fast-food store before robbing her will appear in court today.
The Westminster man approached the 18-year-old woman near Hungry Jacks on Warwick Road about 9pm last night.
Police allege the man demanded cash before threatening the teen and asking her to perform sexual acts on herself. He eventually made off with her bag.
Warwick detectives have charged the man with robbery and aggravated sexual coercion. He is due to face Joondalup Magistrates Court today.
Two other men, both 20, were charged with criminal damage after they allegedly broke two windows at the same Hungry Jacks store.
