Tony Mokbel 'Critical' After Prison Stabbing

Drug kingpin Tony Mokbel is in a serious condition after being stabbed at the same Victorian prison where fellow gangland identity Carl Williams was killed.

Mokbel was reportedly barely conscious before being airlifted to hospital after the attack on Monday afternoon.

10 News First reports the 53-year-old's condition has worsened and he was listed as “critical” on Monday night. Earlier reports put him in a stable condition.

Ambulance Victoria was alerted just before 4pm that a man had suffered multiple stab wounds.

The stabbing comes just a week after the Melbourne's Herald Sun reported Mokbel had disrupted a stand­over racket at the maximum security prison, which houses about 400 inmates.

It's the same prison where, in April 2010, gangland killer Carl Williams was beaten to death with part of an exercise bike.

Mokbel was sentenced to 30 years in prison in 2012.

He fled to Greece in 2006 while on bail during a trial on cocaine importation charges. He was arrested in 2007.

Born Antonios Sajih Mokbel in Kuwait to Lebanese parents in 1965, his family migrated to Australia when he was eight.

He grew up in poverty in Melbourne's northern suburbs.

As a teenager, Mokbel started out at his brother's pizza shop but within six years became the head of a multi-million dollar drug empire.
