The men were all convicted of robbing a post office in Leeds
Three men from West Yorkshire have been convicted of stealing more than £1m from a Securitas van.
Dennis Slade, 33, and Richard Pearman, 34, of HMP Wakefield, and Michael Baxter, 33, of Park View Court, Leeds, were found guilty of robbery.
They were also convicted of conspiracy to murder, arson, criminal damage and handling stolen goods, at a separate trial last year at Leeds Crown Court.
The Securitas van robbery took place in Woolston, Warrington, in March 2006.
West Yorkshire Police said Slade and Pearman had also been convicted of a separate robbery at the Cross Gates Post Office in Leeds in December 2007.
Baxter, and another man, James Hudson, 26, whose address was given in court papers as King Alfred's Drive, Leeds, pleaded guilty to the Cross Gates robbery, in which a digger was used to smash through the wall of the post office.
Slade and Pearman were also convicted of conspiring to rob a Sainsbury's store in Colton, Leeds.
Baxter and Hudson pleaded guilty to conspiring to rob the store.
A West Yorkshire Police spokesman said: "These investigations demonstrate the dedication and professionalism of detectives to bring serious and organised criminals to justice.
"The convictions of these men demonstrate the specialist skills West Yorkshire has to ensure the most serious criminals are put before the courts and convicted."
The men will be sentenced at Leeds Crown Court on 12 February.
