"We were walking home and I suggested we catch a bus and I was like nah we'll just walk," a friend of the boy who was attacked told 9News.
"We jaywalked across the road and a group of cricketers started saying to us 'oh yeah you should get hit by a car' and then came up behind my mate.
"I legit thought my mate died for a solid minute and a half. I'm going off at them and people are pulling over in their cars."
