Senior investigating officer, Detective Chief Inspector Mark Bellamy said: “It is now a week on from the murder and our enquiries are very much continuing at speed as we look to apprehend those suspected of being involved.
“We have previously appealed for dash cam footage of a grey Skoda Karoq registration YB69 MUP which was found burned out at the bottom of The Wrekin last Tuesday night.
"We believe the vehicle is linked to the shooting.
“Two more vehicles have now been seized by us which we’re also interested in as we believe they may also be linked.
"They are a white Toyota IQ A059 UOX and a VW T-Cross grey GK20 FXR.
“I would continue to ask anyone who has dash cam footage of these vehicles, or maybe remembers seeing them, in Telford last Tuesday, or in the days leading up to last Tuesday, to either get in contact with us through the major incident public portal, or if they don’t want to provide their details or come through police they can contact Crimestoppers anonymously.”
Details of the Skoda Karoq are being circulated on digital road signs across Telford.
