Police have arrested and charged Frank "Hollywood" Bacic for refusing to help their investigation into the killing of a senior Hells Angels member.

Local Court Magistrate Leslie Mabbutt granted 36-year-old Mr Bacic bail on a $250,000 security bond with strict conditions, including an agreement not to associate with anyone from the Hells Angels motorcycle club.

Senior Hells Angels member Steve Mitrovic was gunned down on January 16 at his Wetherill Park business Dynamic Transport after a fierce argument with a group of men that included Mr Bacic.

More than 300 Hells Angels from around the country attended the funeral of Mr Mitrovic, a 45-year-old father of three, along with members from other bikie clubs such as the Rebels and Red Devils.

Barrister Brett Galloway, representing Mr Bacic, said police wanted details of the arrest to be suppressed until Tuesday.

"This is the first case I have done in 30 years where police have sought to lock someone up for their own protection. I thought that was the police's job to protect members of the public," he said.

As Fairfax reported at the time, the death is linked to an argument over a debt of Mr Bacic, who knew Mr Mitrovic and was taken there after trying to get money from George Alex, another businessman associated with Mr Mitrovic.

Police confirmed Mr Bacic had been bashed and taken to Mr Mitrovic's business by a group of seven men they now want to interview.

A senior police source said a person of interest includes the son of a current Hells Angels member.

"There has been no retribution from the Hells Angels because it had nothing to do with the club, and the person they would want is now not here – we believe he has left the country," the police source said.

He confirmed rumours that the wanted man appeared to be drug-affected at the time of the shooting.

But a senior Hells Angels figure denied any member or son of the club had anything to do with the murder.

"That's just wrong," he said.

Homicide squad police have obtained CCTV footage that captured seven men arriving at Mr Mitrovic's business but declined to comment on Mr Bacic's arrest.

Mr Bacic, charged with concealing the serious indictable offence of another person, faced Parramatta Bail Court on Saturday and is expected to be released on Wednesday or Thursday.

The matter is next listed for a mention on February 12 at Sydney's Downing Centre.
