Around 7:50 pm that day, a Silver Suzuki Vitara was traveling along High Street at Sippy Downs when two unidentified individuals approached the car on e-scooters.

The pair discharged a fire extinguisher into the car before fleeing.

A 29-year-old male driver, and a five-month-old baby girl, sustained minor injuries.

The girl’s mother told 9News the child had to be taken to hospital to have her eyes washed out with saline.

The fire extinguisher believed to have been used in the attack was found nearby on Stringybark Road, Sippy Downs.

Investigators are urging residents and businesses who were in the vicinity from 7:30 pm to 8:20 pm that day, and who may possess pertinent information, CCTV, or dashcam footage, to reach out to the police.
