UPDATE: A teenager claims she was terrorised by three people dressed as clowns as she was walking from a bus stop in Perth’s southern suburbs on Saturday night.

In an alleged incident thought to have been inspired by the film adaptation of Stephen King’s novel It, 16-year-old Rastana Baker said that she was scratched on the neck after pulling away when grabbed by one of the trio in clown masks in Baldivis.

The girl said she had been walking along Eighty Road to a friend’s house about 7.15pm when a car stopped and three people got out wearing clown masks and dark clothing.

“I didn’t want to look back a second time, but I could tell they were behind me when I heard them laughing,” Rastana said.

“When I did turn around, I saw the wigs and clown faces. They were running in and out of the bushes, running up to me.”

Rastana claims that when she tried to run away, one clown grabbed her by the shoulder.

She said she broke free and ran to her friend’s house and called police.

Rastana said the incident had left her scared to go outside at night. “For people that are out there just doing this for fun, it is not for fun and it can actually traumatise somebody,” she said.

Sgt Andrew Maher said police were concerned such instances could lead to a more serious incident. The big-screen adaptation of King’s bestselling novel has smashed box-office records.
