Two rival gangs fired on each other in a suburban street a month before a fatal shooting outside a Melbourne boxing event, a court has heard.
Ali El Nasher, 29, is seeking bail in Melbourne Magistrates Court, charged with the attempted murder of Joseph Abouchaya in suburban Kensington on March 1.
In opposing bail, Detective Senior Constable Matthew McKenzie described the public shooting as an "escalation" in an ongoing turf war between two gangs.
El Nasher and his brother Abdullah, 27, are alleged to be members of one of the gangs.
He said the elder El Nasher was involved in a shooting outside his Brunswick home on February 5, with gang members firing at each other as they drove down the street.
Det Sen Const McKenzie added bullets were left strewn across the street and there was damage to a neighbouring house and two cars.
The following month, tensions were high between the groups at the boxing event, organised by underworld figure Mick Gatto.
Det Sen Const McKenzie told the court the El Nasher brothers "exchanged some verbals" with kickboxer Omar Bchinnati and his associates during the event.
"Many witnesses described it as quite heated," he told the court on Tuesday.
A witness said Mr Gatto tried to calm the groups down before they were asked to leave.
About 15 minutes later, multiple shots were fired outside the venue, seriously injuring Bchinnati and killing his associate Benjamin Togiai.
Abdullah El Nasher and Osamma Allouche are charged with murder and attempted murder.
Mr Abouchaya was with the victims and he ran back into the foyer before he was allegedly shot by El Nasher's associate Mikhael Myko, who is also charged with attempted murder.
El Nasher is alleged to have stomped on Mr Abouchaya's head three times as he lay incapacitated on the floor.
Det Sen Const McKenzie said Mr Abouchaya would have died from injuries sustained in the attack if it were not for medical intervention.
He urged Magistrates Donna Bakos to oppose bail, citing El Nasher's "significant history predominately related to weapons and violence".
The detective said El Nasher is also a person of interest in several stalled investigations, including a shooting in March 2018.
"There are witnesses refusing to make statements because of fear of retaliation," Det Sen Const McKenzie said.
El Nasher's lawyer argued he was acting in self-defence as Mr Abouchaya was carrying a gun.
Seated in court during the proceedings were supporters of El Nasher and the family and friends of Mr Togiai.
The bail application will continue on December 18.
