COPS probing a petrol bomb attack on the home of Celtic boss Peter Lawwell have released details of two cars which were spotted "acting suspiciously" in the area at the time. 

Officers are hunting for the occupants of a light coloured hatchback - possibly a Mercedes A Class - and white Fiat 500 and believe they may hold the key to their enquiries. 

Lawwell and his family were last week forced to flee their Thortonhall house, South Lanarkshire, in the early hours of Wednesday morning when a thug poured fuel onto three motors in the driveway and flames spread to the property's garage.

The outgoing Celtic chief executive later told of the "devastation" the incident had caused to his family. 

Glasgow Times:

Police last week identified one male suspect and today say the two cars were seen acting suspiciously in the Peel Road area at the time of the attack. They were last spotted driving along South Road, in the direction of Queensway, East Kilbride. 

Detective Inspector Susie Cairns said: “Over the past week we have continued with our detailed enquiries into what happened in our efforts to trace the person, or persons, responsible.

“We know that one man poured an accelerant on the vehicles. What we want to trace now are these vehicles, seen around the Thorntonhall area during the early hours of Wednesday, May 19.

“I would ask again for anyone who may have been on the surrounding roads, or the Queensway, and recording with dash cam, to provide any relevant footage to officers as soon as possible.

"Also for anyone with private CCTV footage in these areas to check their system to see if either vehicle is captured. We're keen to find these cars and their occupants to understand why they were in the area at this time." 

The male suspect officers are seeking to trace is described as around 5ft 10ins and of slim build. He was wearing black joggers, a black hooded jumper with the hood up, black trainers and a face mask.

Last week, Lawwell said in a statement: “This has been a devastating attack on myself and my family, the effects of which will stay with us all for a long time.

"I am, of course, extremely relieved that everyone is safe. I would like to thank my wife and my family for their support and for the strength and courage they have shown during such a difficult time.

“Naturally my family has been deeply affected by these events. This is a hugely challenging time but we will make sure we stay strong and we will get through this together."
