Three men were arrested on suspicion of murder today after father-of-one Mark Short died at a Droylsden pub in May.
The men, aged 27, 29, and 37, are being questioned by officers after 23-year-old Mr Short was injured in a targeted attack at the Cotton Tree on May 25.
Three other men were injured in the attack but their injuries are not life threatening.
A family statement said Mr Short’s killers were ‘cowards’ and that the amateur boxer would live ‘in our hearts forever’.
Detective Chief Inspector Denise Worth, of the Major Incident Team, said: “We still need information about the gunman, his accomplices or conspirators. I understand that it can be sometimes difficult to speak to police officers, but I want to reassure everyone that they can be dealt with in the strictest confidence.
“Mark was a young man with everything to live for so it is important that people think about what they know and get in touch, no matter how insignificant that information may seem.”
Mr Short was jailed in February 2009 after breaking a shop assistant’s jaw while on bail for stealing a car.
Detectives were questioning three men, aged 18, 21 and 34, on suspicion of murder and assisting an offender but they have been bailed until July 30.
A woman arrested on suspicion of conspiracy to commit murder and possessing a class A drug remains on bail until August 6.
