He was recenly photographed with Ali El Nasher, who was recently charged with attempted murder over the shooting of three men outside a boxing event in Kensington in March.

He is also an associate of Nabil Maghnie, also known as Nabil Moughnieh, who was granted bail last month on the condition he attend a drug rehabilitation clinic, after he was allegedly involved in a high-speed crash with cocaine in his system.

Mr Maghnie once drove himself to hospital, after being shot in the head for a second time.

According to police and underworld sources, Anthony Mokbel sided with Mr Maghnie in a violent gang feud with underworld figure Mohammed Oueida, who was the target of a sustained fire-bombing campaign last year.

In July last year, two cars and a garage at a Craigieburn property linked to Mr Oueida were destroyed in a firebombing attack that caused more than $100,000-worth of damage.

The Age does not suggest Mr Mokbel or Mr Maghnie were involved in the arson attacks, nor that Mr Oueida was responsible for the attack on Mr Mokbel.

Mr Mokbel appeared before the Melbourne Magistrates Court in 2015 after he was twice caught driving while suspended in Oak Park and Cobram.

In 2014, he faced a Gold Coast court over an altercation with a flight attendant on a Jetstar flight from Melbourne.

Mr Mokbel became aggressive towards a female flight attendant after being told “multiple times” to switch off his phone on the flight.

He was fined $300, placed on a good behaviour bond, and ordered to pay $1151 in costs.

Mr Mokbel did not respond to calls from The Age.
