The Noiseworks frontman was quizzed by cops for 30 minutes after an elderly man received leg injuries in the collision with Stevens' BMW in Point Piper, Sydney.

A police probe is ongoing, but Stevens insists the crash was an accident and revealed he tended to the 69-year-old pedestrian while they waited for paramedics to arrive.

He tells the Sydney Daily Telegraph, "I'm not all right. I'm not all right. It's a blind spot. I didn't see him. I was taking a right. I did call the ambos (ambulances). I tried to help (by) keeping him still."
