A former loyalist gun-runner has been murdered in what police described as a frenzied attack in the east of Glasgow.
Police said the attack on Lindsay Robb was extremely violent
Lindsay Robb, 38, originally from Lurgan, was assaulted in his car on Saturday evening outside shops in Gartloch Road, in the Ruchazie area.
Police said they have been "keeping an open mind" about the motive.
Mr Robb was jailed for 10 years in 1995 for involvement in a UVF gun smuggling plot but was released in 1999 under the terms of the Good Friday Agreement.
Following his release, he moved to Scotland and was living in Airdrie with his wife and two children.
Strathclyde Police said Mr Robb had been working as a part-time gardener.
He was attacked in his Ford Fiesta at about 1730 GMT after dropping colleagues off outside an off-licence.
Police said the area was "very busy" at the time, with people making final preparations for Hogmanay.
About 20 officers have been deployed to search for the killer or killers.
They have been studying closed circuit television footage and have appealed for witnesses.
In particular, they want to speak to the driver and passenger of a white van which was parked behind Mr Robb's car.
Police said there was nothing to indicate a connection between Mr Robb's murder and his conviction for gun-running but they were looking into his background as part of the inquiry.
Describing the attack as "vicious", Detective Chief Inspector Alan Buchanan told BBC Scotland: "We certainly have no indication that the reason he was attacked is anything to do with his past activities.
"We're keeping an open mind as to why he was murdered but just now we're appealing for information from any witnesses who can come forward and help us with this inquiry."
Mr Buchanan said it was "too early to say" if Mr Robb knew who attacked him.
"These attacks tend not to be random but we don't have any indication that he did know his attacker," he said.
Mr Robb was jailed for attempting to smuggle guns through Scotland to the Ulster Volunteer Force.
At the time of his conviction he was a leading member of the Progressive Unionist Party, which was involved in peace deal talks with the UK Government.
He served the first part of his sentence in Scotland but was later transferred to Maghaberry Prison in Northern Ireland.
Mr Robb changed his allegiances to the Loyalist Volunteer Force in Maghaberry and became the first member of the LVF to be freed under the early prisoner release scheme, which formed part of the Good Friday Agreement.
