Justin Bieber is being investigated for an alleged assault.

The 16-year-old pop star reportedly hit a 12-year-old boy while playing a game of laser tag - an infrared points scoring gun game - in Canada. Although the child in question suffered no visible injuries, the Royal Canadian Mounted Police are in the process of interviewing witnesses who were present at the time of the alleged incident.

However, Canadian blog ZackTaylor.ca spoke to staff at the laser tag centre and they claim the 'Baby' hitmaker was cornered by a group of eager fans and "accidentally hit the kid while running away".

Meanwhile, Bieber has confessed he sulked and cried like a baby when he failed his first driving exam and refused to sit in the Passenger seat of the Range Rover his mentor Usher bought for him as a 16th birthday present.

Writing in his book 'First Step 2 Forever: My Story', Justin - who passed his driving test in April - said: "There was no way I was getting in the passenger seat, bawling like a ten year old. I felt every car driving by was taunting me. Some girl drove by, putting on mascara as she weaved down the boulevard - but she sure had a driver's licence, didn't she?

"Some dude cruised by in a truck, smoking a cigarette, which he tossed on the street like the world was his ashtray. I bellowed after him, 'I hate you!' It felt so good. I bellowed at the next guy, 'I hate you too! And I hate you! And I hate you!' "
