A MAN armed with a rock threatened two people at the Margaret River Skate Park on Thursday night.
Margaret River Police Sergeant Brett Cassidy said the victims, aged in their 20s and 50s, were frightened by the threats especially as English was their second language. The incident happened at 7.40pm and police are calling for witnesses to help capture the man.
"We've got a person of interest; he's in his 30s," Sgt Cassidy said.
There has been some vandalism in the area lately including a smashed window at the nearby Zone Room, and police believe this could be linked to the same culprit.
Anyone with information can contact police on 9757 2222 or call Crime Stoppers on 1800 333 000.
