A 25-year-old man is beginning an eight year sentence after he was found guilty of the manslaughter of a 38-year-old man who had tried to rob him.
Carl Lindsay from Walkden, Greater Manchester, stabbed Stephen Swindells after he and three accomplices arrived at Lindsay's home armed with a gun.
Mr Swindells died later after he was found discovered collapsed in an alley.
His three accomplices were found guilty of robbery and firearms offences and sentenced to fourteen years.
Manchester Crown Court heard how Mr Swindells, from Rockley Gardens, Salford, went to Lindsay's flat at 2145 GMT on 27 February 2003 with the intention of robbing him.
Robbery and firearms offences
When Lindsay opened the door, to be confronted by him and three accomplices who were armed with a gun, he fetched a Samurai sword and stabbed Mr Swindells four times.
Mr Swindells died later in Hope Hospital after he was found in an alleyway between Strawberry Road and Broad Street in Pendleton.
David Ryan, of Salford, Darren Ashton of no fixed abode and Michael Page, also of no fixed abode, were all convicted of robbery and firearms offences.
They were sentenced to 14 years.
Det Chief Insp Sam Haworth said: "Four men including the victims had set out purposefully to rob Carl Lindsay and this intent ultimately led to Stephen Swindell's death.
"I believe the sentences passed today reflect the severity of the circumstances."
