Police have released new CCTV footage of two people on an e-bike as a manhunt continues for a duo who sprayed a fire extinguisher into a car and injured a five-month-old baby.

Teasdale said smoke filled the car, which left Leon unable to see or breathe.

“He yelled out to them ‘I’ve got a baby in the car, I’ve got a baby in the car’ and they didn’t care at all,” Teasdale told 9News earlier this week.

Leon pulled up abruptly at a nearby bus stop and rushed out of the car to pull Pixie from the back seat.

“As soon as he opened the door she was covered in white powder,” Teasdale said.

“Her eyes were just massive and her mouth was wide open, she was pretty much in shock.”

Police believe the fire extinguisher was stolen from a nearby car park on Courage Street in Sippy Downs earlier that night.

Detectives have today released footage of two people riding in tandem on the bike in an underground carpark.

Earlier CCTV footage shows the two driving up the street and spraying the extinguisher behind them.

After the incident, Pixie was rushed to hospital, where nurses frantically worked to flush the chemicals from her eyes.

Teasdale said she heard her daughter scream and saw her covered in red rashes with bloodshot eyes.

“It was the most horrible scream I’ve ever heard in my life,” she said.

“I actually had to leave and one of the nurses had to come in and hold her down for me.”

Teasdale said the pair should “grow up”, take accountability for their actions, hand themselves in and “stop terrorising the neighbourhood”.

“It’s disgusting to be honest,” she said.

“You never know who’s going to be in the car.

“It could’ve been someone with respiratory issues, it could’ve been a newborn baby, it could’ve been an elderly person.”
