Death threat by Vic bikie alleged in court

A senior Mongols bikie in Victoria allegedly threatened to kill a man and make it look like suicide.

The potential victim has not made a formal statement against Shane Middleton, but police say the allegation is one of many reasons the bikie should not be granted bail.

Middleton, a Mongols sergeant-at-arms, will be committed to trial on drugs and weapons charges after pleading not guilty.

He applied for bail in the Melbourne Magistrates Court on Thursday, and will learn on Friday if it is successful.

Detective Senior Constable Andrew Broad opposed Middleton's release, saying police believed Middleton could offend, interfere with witnesses and fail to appear in court.

Investigations were continuing into a suspected threat by Middleton, 26, who allegedly called the man a "f***ing rat" and dog, before he was taken into custody.

"Mr Middleton then threatens he would kill him and make it look like suicide," Det Sen Con Broad said.

Middleton is not charged over the allegation.

The police officer told the court he had concerns relating to another witness in an alleged armed robbery case, separate to the drugs and weapons charges.

He said an associate of Middleton's had approached that witness, offered him $5000 and said: "Man, you've got to pull your statement against Shane."

"If this can be orchestrated while Mr Middleton is in prison, I fear it will be a lot worse if released," Det Sen Con Broad said.

The detective later conceded, under pressure from Middleton's barrister, Christopher Farrington, there was no evidence Middleton had arranged the alleged witness interference.

Mr Farrington said the argument was farcical.

Middleton's mother offered a $300,000 surety, he had ties to the area and employment was available, he told the court.

The court heard Middleton had suffered post-traumatic stress disorder, and would undergo mental health treatment and receive court-related support if granted bail.

If released he would live with his co-accused partner Renee Comeadow, who is on bail and has also been committed to trial after pleading not guilty to a drug charge.

The two have a child.

The court has not heard all of Mr Farrington's arguments, which will continue on Friday before a bail decision is made.
