Detectives are still investigating an armed robbery at a Bradford supermarket for which a father-of-two was jailed for 14 years.
A police chief said today that members of the professional armed gang were still at large and detectives were still trying to track them down.
During the early morning attack on the Morrisons store at Five Lane Ends in July last year, two masked robbers held a security officer hostage at gunpoint before escaping with £210,000 in cash.
A loaded revolver was later recovered from one of the gang's getaway vehicles, but Bradford Crown Court heard that only £380 of the cash delivered by Securicor that day had ever been traced.
Anthony Morgan, 36, from Ramsgate Road, Manchester, was convicted by a jury at the end of a seven-day trial of being involved in the planning, organisation or execution of raid. He had been caught by police in Dover trying to flee the country with his family.
The robbers posed as motorcycle couriers before they grabbed security officer John Riley.
After taking him into the store they ordered staff in a cash office to let them inside where the money was put into a holdall.
As they fled one of the robbers pointed a gun at a member of the public telling him not to be a hero. The raid was captured on CCTV cameras and shown to the jury.
Morgan denied the offence but his fingerprints were found on crash helmets left by the robbers and the £380 was recovered from his home.
Jailing him, Recorder Malcolm Swift QC said: "The evidence drives me personally to the conclusion that you were one of the two robbers present in Morrisons.
"The only thing that marks it out as being any different from the most serious offence of robbery was that the weapons you had were not fired."
Detective Chief Inspector Colin Sutton, who lead the inquiry, said: "The police officers at Eccleshill did a very thorough job, but our inquiries are continuing because we think others were involved."
A second man Sean Caherty, 31, of Hedley Walk, Manchester, was jailed for five years for his part in providing false number plates for the getaway car.
