Paul Gallen has been photographed with bike murder accused Haydn Forbes

NRL star turned fighter Paul Gallen has been pictured at a Glitter Strip boxing gym with Haydn Forbes, one of 10 men charged with Shane Bowden’s execution-style slaying.

Former NRL star turned fighter Paul Gallen has been unwittingly photographed with one of notorious Gold Coast bikie Shane Bowden’s accused killers.

Gallen was photographed at a Glitter Strip boxing gym recently with fans including Haydn Forbes, one of 10 men charged this week with Bowden’s execution-style slaying last October.

Forbes - the private school-educated, clean-cut son of another infamous bikie, Nick ‘The Knife’ Forbes - was photographed alongside Gallen at the gym in May.

The ex-Blues and Cronulla Sharks skipper was on the Coast ahead of his fight with Australian heavyweight champ Justin Huni in Sydney last month.

Haydn Forbes was arrested in police raids last weekend and there’s no suggestion Gallen had any knowledge of his alleged involvement with the Mongols bikie gang, accused of planning and executing Bowden’s murder.

Bowden was shot 21 times by hooded gunmen in the driveway of his Pimpama home on October 12 as he returned from a late night gym session.

Police allege he was sprayed with bullets from a machine gun pistol and a shotgun.

They also have also alleged a tracking device was placed under his car in the lead-up to his murder.

The Courier-Mail can also reveal that an alleged Mongols associate previously named in court as a person of interest in the Bowden killing is the latest man charged over his death

Jake Taylor, 26, of Bellbird Park, was charged with murder on Tuesday and is due to appear in Brisbane Magistrates Court on August 2.

Taylor was charged last November with supply of firearms, 12 counts of possessing a modified firearm and one count of possessing explosives.

Haydn Forbes, son of Mongols outlaw motorcycle gang heavyweight Nick ‘The Knife’ Forbes, is behind bars, accused of the execution-style murder of Shane Bowden.

Detectives also allege that Taylor used bought two vehicles later found burnt out nearby the Bowden murder scene, under a false name.

Bowden was a former Mongol who police say defected back to his old gang, the Finks, before he was gunned down.

He and Nick Forbes were members of the Finks ‘Terror Team’ of enforcers before ‘patching over’ to the Mongols with other key gang members in 2013 when the-then Newman Government launched its massive bikie crackdown.

Nick Forbes allegedly later became the Mongols national president.

He has not been charged over Bowden’s death and there is no suggestion he has any involvement.

Contacted for comment by The Courier-Mail, Gallen said: “I’ve got nothing to say mate, nothing to say.”

A spokesman for Channel Nine, where Gallen now works as an NRL expert, said the ex-footballer was at the gym to spar with local boxer Faiga Opelu in preparation for the Huni fight.

“Paul confirmed there were about 50 people in the gym that day, 90 percent of whom he did not know, including Mr Forbes,” the spokesman said.

“As someone in the public eye he gets snaps all the time with any fans who want one or who jump into photos, the vast majority of whom he of course does not know.

“He does not know Mr Forbes in any way.”
