Former drug kingpin and gangland figure Tony Mokbel has been stabbed in prison in Victoria.
Police this afternoon confirmed a man was being airlifted to hospital in a serious condition after a stabbing at Barwon Prison, at Lara.
Aerial footage from the scene shows a bare-chested man being treated by a number of paramedics outdoors, with multiple media outlets reporting Mokbel was attacked in an exercise yard of the high-security jail.
He was taken to hospital by helicopter.
A second inmate, aged 31, was taken to hospital by road ambulance and was also in a serious condition.
No prison staff were injured.
Mokbel, 53, hit headlines in recent weeks after news broke that his former lawyer had acted as a police informer, dishing dirt to detectives to help secure convictions.
Famously captured in Greece in 2007, Mokbel has since been sentenced to a 30-year jail term for drug crimes and must serve at least 22 years behind bars before being eligible for parole.
But the lawyer informant scandal has opened a possible window of appeal to Mokbel.
The stabbing comes a day after News Corp ran an article headlined "Tony the enforcer" about Mokbel's rise as a "feared prison big-wig".
The Herald Sun reported that Mokbel intervened to stop an extortion attempt of a 19-year-old prisoner in jail for the first time.
"When the Islanders were spoken to, on [Mokbel's] orders, the scared young prisoner was left alone immediately," the newspaper reported.
