“I just clutched my shoulder straight away and pulled off to the side of the road.
“[The block’s] got a nice bit of weight to it too. Straight up to the right a bit and it probably would have got me straight between the eyes and I wouldn’t be here talking, I’d be in the morgue now.”
Mr Wells was hospitalised over the incident.
P-plater Morgan Price, 18, was also targeted Monday night, with a rock smashing the bottom of her windscreen as she drove along the same stretch of road, which has a speed limit of 70 kilometres an hour.
“I was just driving down this road and a guy walking across the side road has thrown a brick or a large rock at my windscreen and it’s smashed it and broke my windscreen wiper,” she said.
“It would be a very stupid idea if they keep doing it, they’re going to get caught and they could potentially kill someone so it’s very dangerous.”
Community members online have reported an increase in incidents around a pedestrian bridge on Mandurah Road, with some claiming they had been targeted with rocks, watermelons and water balloons while driving.
