A special service is to be held for a young man gunned down in a post office raid. People are expected to pack St Mark's Church, near the scene of the shooting in the Worcestershire village of Fairfield. More than a hundred officers are hunting the four-man gang linked to the murder of Craig Hodson-Walker on Friday. The men, armed with a handgun and a sledgehammer, blasted 29-year-old Craig Hodson-Walker in the chest during the raid at his parents' business in Fairfield, north Worcestershire. His father Ken was shot in the leg as the men burst into Fairfield Post Office and Stores on Stourbridge Road. The men, who were wearing balaclavas, escaped from the scene on Friday morning in a silver VW Golf which was found abandoned in a nearby road. West Mercia Constabulary said the car was stolen from Solihull on New Year's Eve and had false number plates. Detectives said it was likely that the car had been caught in rush-hour traffic near the post office and urged anyone who saw the vehicle to contact them. Detective Superintendent Jon Groves said the robbers should not be approached. He said: "I am leading this investigation and a team of detectives and staff in excess of 100 are working on this case. "I can assure you that we are determined to bring these offenders to justice as soon as possible. "Any information people may have, no matter how insignificant it may seem, could provide a vital lead. Please get in touch with us." Detectives are investigating whether the incident is linked to three or four robberies that have occurred in the Bromsgrove area over the past several months.
