The Mandurah Aquatic and Recreation Centre has been evacuated after a light panel shattered in the pool area causing “smoke and smouldering”.
MARC patron Gemma Clarke said she heard an explosion about 12.45pm.
“We heard an explosion and thought a bird had hit the glass,” she said.
“We looked up and a light panel had shattered – there was smoke.”
An Emergency WA spokeswoman said the electrical fire had been extinguished and an electrician was on their way.
Patrons have been evacuated while the incident is assessed.
