Detective Chief Inspector Andrew Howard, of Bradford District Police, said: “This gang planned to carry out a series of robberies on cash-in-transit vans in Bradford and Leeds by using Nadeem’s knowledge of when and where the cash collections would take place.
“The weapons seized in this investigation prove they were prepared to use whatever means necessary to get what they wanted. I would like to thank those who supported our team of detectives with investigating these offences which undoubtedly prevented further incidents and brought these criminals to justice.
“These types of offences are thankfully uncommon and police in Bradford continue to work with organisations who deliver and collect cash across the district to make sure their employees can go about their business in safety.”
