Melbourne gangland-linked gunman Mikhael Myko in Vietnam jail after death of Vincent Atulia and Andrew Colivas

Melbourne gangland-linked gunman Mikhael Myko has started the new year detained in Vietnam with no indication of when he could be back home after the death of two Melbourne boxing mates.

Mikhael Myko has been stuck in Vietnam since the death of Andrew Colivas and Vince Atulia.

Melbourne gangland-linked gunman Mikhael Myko has started the new year detained in Vietnam with no indication of when he could be back home.

Mystery surrounds the situation of Myko, who has been unable to leave the country in the four months since the deaths of Melbourne friends Vincent Atulia and Andrew Colivas.

It is not known what, if any, charges he is facing but his issues are believed to relate to what happened to Mr Atulia, 24, and Mr Colivas, 25.

It was reported in the aftermath of the double-tragedy that authorities in the South-East Asian country were investigating whether the pair suffered drug overdoses.

The Department of Foreign Affairs and Trade said this week it was providing consular assistance to an Australian man in Vietnam.

DFAT was initially helping three men in Vietnam in the aftermath of the deaths of Mr Atulia and Mr Colivas.

But two of them, believed to be brothers from Melbourne, were able to get out of the country some weeks later.

“Owing to our privacy obligations we are unable to provide further comment,” DFAT said.

Vietnam takes a hard line on drug crimes and still imposes the death penalty for high-level offending.

Myko, 31, did jail time over the infamous Kensington fight-night violence of 2019.

He had been with brothers Ali and Abdullah El Nasher for a boxing event at the Melbourne Pavilion when a slanging match broke out with men on another table.

Things turned to bloodshed outside where Abdullah opened fire on their foes, killing young father Ben Togiai and wounding another man, Omar Bchinnati.

Myko shot four times at another man, hitting him in the abdomen and leg.

After the victim fell, Ali El Nasher stomped and punched him and Myko struck him with his handgun.

Abdullah and Myko fled to New South Wales but were arrested by police a week later.

Myko served 806 days after pleading guilty in the Supreme Court to recklessly causing serious injury.

Abdullah is doing a minimum 22-year jail term for the murder of Mr Togiai.

Ali was released from prison late last year for his role in the violence.

Underworld sources say bad blood towards him over what happened at The Pavilion continues to linger.
