The Parole Board says a notorious violent criminal is back in prison because he poses an undue risk to the public.
John Gillies was jailed for 12 years in 1993 for the attempted murder of a police officer with a screwdriver - an attack that left the victim permanently disabled.
Gillies has more than 100 convictions, including assaulting two other police officers and possession of Class A drugs in 2005, for which he was sentenced to seven years in jail.
The board approved his release in April 2011 but he was jailed later in the year for breaching his conditions.
Gilles was released again in October 2011 but midway through February an application was made to return him to prison on the basis he posed an undue risk.
The board says a decision will be made next week on whether Gillies will be allowed to continue his parole, or serve out what remains of his sentence.
