LAKESIDE Joondalup shopping centre was evacuated on Thursday night, after a sprinkler head was knocked off in the carpark.
A spokeswoman for the centre said the incident occurred about 6pm when a car struck the sprinkler, causing a stream of water to flow from the top level of the carpark into the first floor.
The incident triggered a direct alarm to the Department of Fire and Emergency Services, who attended the centre.
David Ham was getting a haircut when he was told he would have to leave the centre.
“At Lakeside Joondalup shopping centre getting a haircut when the fire alarm goes off,” Mr Ham wrote on Facebook.
“Everyone is standing around in the car park and I have half a haircut.”
