Prominent Co Armagh republican Colin Duffy has escaped injury during a gun attack on his house.
It is understood at least two shots were fired into the family home in Lurgan in the early hours of yesterday.
Mr Duffy was at home with his wife and three children when the attack took place. No-one was injured.
A window in a downstairs living room was shattered after two loud bangs were heard shortly before 1.30am.
A police helicopter circled the area for a short time after the shooting before officers arrived.
Forensic officers returned to the scene at around 12.30pm yesterday.
It is not known who was behind the gun attack.
Superintendent Wendy Middleton said: "Police received a report of shots fired in the Forest Glade area of Lurgan during the early hours of Tuesday.
"Police attended the area, and enquiries are ongoing.”
Attempts have been made to kill Mr Duffy in the past.
He was one of three men targeted by the UVF as they left Lurgan RUC station in 1990 after signing bail.
Local man Sam Marshall was killed in the attack, which many believe involved collusion.
In 1995 he was convicted of killing former UDR man John Lyness but this was later overturned after a key witness Lindsay Robb, who was a member of the UVF, was arrested for gun running in Scotland.
In 1997 Mr Duffy was was charged with killing RUC officers, John Graham and David Johnston, while on foot patrol in Lurgan town centre but the case was later dropped. He has always denied any involvement.
His solicitor Rosemary Nelson was killed when a loyalist bomb exploded under her car in 1999.
In 2012 he was found not guilty of killing two British soldiers at the former Massereene British army barracks in Antrim and released after spending a lengthy period on remand.
Sappers Patrick Azimkar and Mark Quinsey were shot dead as they took delivery of a pizza at the gates of the base in March 2009.
A current trial involving Duffy and two co-accused, Alex McCrory and Harry Fitzsimmons, was recently adjourned for several weeks.
Mr Duffy (51) is accused of 'preparing and directing terrorism' and IRA membership.
The charges are linked to a gun attack on a PSNI vehicles on Belfast's Crumlin Road in December 2013.
All three deny the charges.
The attack on Mr Duffy's home come amid after a recent increase in violence.
Last week journalist Lyra McKee was killed during rioting in Derry.
The group known as the 'IRA' – sometimes referred to as the New IRA – said in a statement to the Irish News it was responsible for shooting the writer and apologised to her partner, family and friends.
A funeral service for Ms McKee will take place at St Anne's Cathedral in Belfast today.
