THE son of a murdered shopkeeper today made a plea for help to catch his father's killer.
Abbas Ali, 25, spoke on behalf of his family after Javaid Ali died from stab wounds following a robbery at his store.
Mr Ali, 48, was stabbed on June 15 in Sunshine Grocers in Green Road, Paisley.
He lost his fight for life in the town's Royal Alexandra Hospital on June 29. Police are treating his death as murder.
Abbas, one of Mr Ali's three sons, said during his appeal: "Our family is devastated at the loss of my father. He was a wonderful father, husband, son and friend.
"He meant so much to us and it is heartbreaking we will never see or speak to him a gain
"I cannot put into words the suffering this has caused my family.
"I would urge anyone to come forward and help police find whoever did this."
DCI Duncan Sloan, who is leading the murder inquiry, described the killing as a "horrendous and vicious attack"and said he believed information could come from local people.
Detectives are keen to speak to a female driver, in her 30s with short brown hair, who stopped outside the shop shortly after the incident.
They also want to trace a man carrying bread near the store at about 3pm on the day of the attack and a woman, about 18, wearing an apron and carrying Aldi shopping bags, walking towards Green Road.
Two years ago, Mr Ali bravely fought two robbers, one of whom had a crossbow, while the other had a knife.
