New law to keep Hoddle St killer in jail

A new law has been created especially for Hoddle Street mass murderer Julian Knight to keep him locked in jail.

The legislation will be introduced in the Victorian Parliament on Tuesday and will severely restrict the circumstances in which the Adult Parole Board can grant Knight parole, News Corp Australia reports.

The law, which will apply solely to Knight, will only grant him parole if he is "in imminent danger of dying or is seriously incapacitated" and as a result "no longer has the physical ability to harm any person".

Knight, who killed seven people and injured 19 during a shooting rampage in 1987, was sentenced to life in prison with a 27-year non-parole period.

He is eligible for parole in May, but Victorian Premier Denis Napthine has vowed Knight will never be released while he is premier.

Knight has been declared a vexatious litigant after many court appearances relating to his parole and other matters.

Just last month the 45-year-old was alleged to have been involved in a prison assault that left another inmate in hospital with a broken jaw.
