A PERTH shop owner has slammed the vandals who went on a crime spree in the CBD.

Joan DellaValle had two windows broken at her salon as businesses along Barrack Street were targeted in the random attack near Forrest Chase on Saturday night.

“Nothing was stolen, (the vandals) didn’t get in (to the shop), they didn’t take anything,” she said.

“It’s pure vandalism and I think they need help.”

At least 16 windows from 11 separate businesses were damaged along the Barrack Street strip.

Another two panels outside the Myer building were also shattered, raining shards of glass onto the seating below.

More than half of the glass lining the stairs up to the Forrest Chase footbridge was also smashed.

Repair crews put wooden boards in place as temporary barriers before crews moved in on Monday.

Restaurants, jewellers and even vacant shops were targeted in the random attack.

Police are investigating if the same person or group is responsible for all the damage.

Anyone with information on the vandalism should call Crime Stoppers on 1800 333 000.
