A spider has sparked a full blown lights and sirens response from multiple police units this morning after horrified neighbours reported hearing a toddler screaming and a man shouting death threats.

Wanneroo Police this morning tweeted that a walker had heard a male shouting “Why don’t you die” repeatedly.

Minutes later police were relieved to discover no one had been injured in the incident — except an unlucky home-invading spider.

The red-faced husband admitted he had a serious fear of spiders and apologised to police for the inconvenience.
