Justin Bieber is being investigated for possible assault with a toy. The "As Long As You Love Me" singer has been accused of hitting a female security guard at a concert venue he was performing at in Ottawa, Canada in November, with a projectile from a child friendly nerf gun.

A source told gossip website TMZ.com that the 18-year-old Canadian popstar was play fighting with nerf guns with his three-year-old brother Jaxon and four-year-old sister Jazmyn, when one of their soft pieces of ammunition hit the woman. The woman allegedly became hysterical and told Justin's team that she was a security guard at the venue and was extremely annoyed. She then filed a police report accusing Justin or someone who was adjacent to the singer of assaulting her.

Police are said to be investigating the incident and have interviewed several people at the venue.
