Justin Bieber's bodyguard is not being investigated by police amid reports he threw an Australian fan's father down a flight of stairs.

A member of the star's security team has been accused of tossing a girl's father through a door with a set of stairs behind it at the Hyatt Hotel in Perth on Friday (06.12.13) after he began yelling that his daughter was being disrespected.

But Western Australian Police have denied reports they were investigating the incident and told gossip website TMZ.com that they weren't aware of anything involving the 19-year-old star's security team.

A source close to the 'Heartbreaker' hitmaker also insisted the attack never took place and the fan's father was merely swiftly escorted out of the hotel after he demanded that he and his kids meet the singer.

Justin has had an eventful time in Australia as customs officials in Brisbane detained him and his entourage on November 24 when they found traces of marijuana on one person.

Australian Federal Police previously confirmed that Justin had to be cautioned for using ''inappropriate language'' at the time.

The singer also came under fire from Gold Coast Mayor Tom Tate after he sprayed graffiti on one of his hotels' external walls.
