Detectives investigating the murder of an 83-year-old retired army officer are following new leads after the BBC Crimewatch programme.

Police said they received more than 60 calls following the appeal on Tuesday night.

Lieutenant Colonel Robert Workman was shot dead at the entrance to his home in Furneux Pelham, Hertfordshire, on 7 January.

Police revealed in the programme that he had been blasted by a 12-bore shotgun filled with ammunition normally used to kill deer.

Detective Superintendent Richard Mann, who is leading the inquiry, appealed for anyone with knowledge of people who used that type of ammunition in the Hertfordshire area to come forward.

We took a very promising call about the possible identity of the 999 caller Detective Superintendent Richard Mann

Police checks have found the cartridges were not available in the Furneux Pelham area.

Police are also trying to trace the person who made an anonymous 999 call hours after the murder in the early on 8 January.

Mr Mann said officers had received calls about the ammunition and about the caller, which they were following up.

"We had a steady stream of calls coming into both the Crimewatch studio and the incident room," he said.

"We took a number of interesting calls about the ammunition used and a very promising call about the possible identity of the 999 caller."
