Police say a 28-year-old man charged with assault was the president of the Bandidos Brisbane chapter when he committed the alleged crime.

The alleged former head of Brisbane’s Bandidos motorcycle gang has been arrested and charged with extortion.

Queensland Police arrested a 28-year-old man on Monday following an investigation into an assault at a Brisbane fast food outlet in 2011.

It’s alleged the assault was a result of an extortion attempt by the man and accomplices against the victims.

Police claim the man was the president of the Centro Chapter of the Bandidos at the time of the incident.

In a statement released on Monday, police said the victims claimed they were assaulted after meeting with the alleged offenders and telling them they didn’t have the money that had been requested.

One of the complainants was knocked unconscious and needed treatment in hospital for his injuries and suffered memory loss.

The arrested man has been charged with assault occasioning bodily harm in company and common assault.

Police say neither of the victims made complaints at the time of the assault out of fear of retribution but decided to come forward following recent media coverage of unrelated extortion claims against the accused and his associates.

Detective Inspector Brendan Smith believes new anti-bikie laws had helped empower the alleged victims to come forward.

“This matter is a clear example of the bullying behaviour used by these gangs as part of their everyday business, but more importantly it shows the change in community attitude as they are no longer afraid,” Det Insp Smith said.

“The new legislation has empowered people to stand up and put a stop to the unlawful behaviour of these gangs.”

The accused will face Brisbane Magistrates Court later on Monday.
