A Kalgoorlie gathering turned from a barbecue into an explosive crime scene after a 41-year-old man allegedly threw butane cans into an open fire.
Police allege the Williamstown man was among people gathered around a fire in a 44-gallon drum in a Plumer Street backyward just before 10pm last night.
"It is alleged a man threw an empty butane canister into the coals causing the can to explode and the can landed approximately 1m-2 metres away," a police spokeswoman said.
He then allegedly threw a second butane canister into the coals, causing the can to explode and fly through the air.
Hot burning coals were thrown over a six-metre fence and landed on the road outside the home.
The canister landed about 3m-4m from the barbecue.
A 41-year-old Williamstown man will be summonsed on the charge of Cause Explosion Likely to Cause Serious Injury to Property and will appear in court at a later date.
