Officers from the Greater Manchester force are offering their largest ever reward for information that leads to the arrest two men wanted in connection with a gun and grenade attack that left a father dead.
The two men are 29-year-old Dale Cregan or 33-year-old Anthony Wilkinson.
Police believe they could still be in the Greater Manchester area. They are both wanted after David Short was killed at his Clayton home.
Dale Cregan is also wanted in connection with the murder of David's son, at a pub just a few months earlier.
