WITNESSES have described hearing an “almighty crash” the moment an allegedly stolen car smashed through an Ipswich street sign and into a fence.

On Wednesday afternoon, a man who had allegedly robbed a house and carried out “multiple carjackings” across Ipswich drove a stolen Subaru across a busy double-lane road, onto the wrong side of the road, before crashing.

A witness said she had been on her way to pick up her two children from school about 2.15pm when she saw the maroon car crash into the fence at Legacy House Ipswich on Brisbane Rd, Booval.

The woman was walking on the footpath on the other side of the road when it happened and said the crash was terrifying and very loud.

Across the road at Eileen St Dental, another witness heard the “almighty” sound.

“He was going down the street towards Brisbane and he’s gone across the road. It was an almighty crash,” the woman said.

The witness said she went to help before noticing police were in pursuit of the driver.

“I thought there had been an accident so I ran over to see if anyone needed CPR,” she said.

“I ran across the road to see if I could do anything and was the first one there.

“Then the police came around the corner and I realised they were chasing someone so I got out of there pretty quickly.”

The alleged offender crashed through an Eileen St Dental sign on the street before smashing through the fence.
