Detectives investigating the murder of a man gunned down outside his home in North Lanarkshire say they have had a disappointing response to appeals.
Father-of-four Tony Wright died in hospital after being shot in Inverkip Drive in Shotts on Wednesday.
The detective leading the murder hunt said the 35-year-old was "no angel" but was a dedicated family man.
Police are keen to speak to the driver of a van and a car seen in the area at the time of the shooting.
The suspect made off on foot across waste ground and was last seen at the rear of Inverkip Drive.
He is described as being white, 5ft 4ins to 5ft 6 ins and was wearing white coloured tracksuit bottoms, a white hooded tracksuit top, a black zipped jacket with light coloured stripes on the sleeves and white training shoes.
Det Supt John McSporran, said: "I'm anxious to speak to the driver of a red Ford Transit flat-bed tipper style vehicle which was seen near to where the shooting happened in Inverkip Drive at around 0650 BST on the day of the murder."
"I am also especially keen to speak to the driver of a new style silver Vauxhall Corsa car that was seen in Inverkip Drive, near to the murder scene, around 0700 BST that morning.
"I am well aware that Tony was 'no angel' and that he had a number of criminal connections. Nevertheless, Tony was also a dedicated family man, who loved his partner Julie and would do anything for their children.
He added: "It is particularly sad that their younger children will grow up without the opportunity to really know their father. The family are devastated by his loss.
"It is completely unacceptable that anyone should be gunned down in a public street.
"People were going to their work, were driving by the scene, children were delivering newspapers.
"Whoever did this had a compete disregard for the safety of the public in general. It is essential that we trace the person responsible and remove this ongoing threat to public safety."
