Traci Grimes recounts a harrowing experience where she was unloading groceries while holding her baby, only to be struck by a brick thrown by a teenager on an e-bike. The projectile narrowly missed her newborn by mere centimeters.

“It could have killed him, honestly,” Grimes expressed to 9News, reflecting on the terrifying incident. “I’m so thankful it got me and not him.”

Grimes, a mother of two from Clarkson, found herself amid a concerning trend of reckless street behavior that police say is on the rise. This alarming pattern involves not only bricks but also rocks and water balloons being thrown at vehicles, homes being vandalized, and dangerous stunts being recorded and shared online.

“I’m so thankful it got me and not him.”

The Clarkson mother-of-two has been caught in what police say is a surge in reckless street behaviour – with rocks and water balloons hurled at cars, homes smashed up and stunts filmed and posted online.

“They came back literally two seconds after we locked our big wooden door and hurled another big brick at our roller blinds,” Grimes said.

“The thought of them probably roaming the street right now with their friends causing even more damage is the most upsetting part.”

WA Police have launched a major crackdown on teens terrorising the area, with helicopters and drones being deployed.

Officers are also ramping up their street presence after the surge in violent incidents.

Joondalup detectives this week launched Operation Moorhead to crack down on dangerous behaviour linked to e-rideables.

Three teens have already been charged, and 11 e-rideables seized are set to be destroyed.
