A second man has been arrested in connection with the murder of a 39-year-old man in Worcester.
West Mercia Police said a man in his 20s was arrested in Birmingham.
A spokesman said a 20-year-old man arrested on Friday had since been "released on police bail for the offence of murder".
Adrian Locke, of Wych Road, Droitwich Spa, died from stab wounds after being found outside 42a Teme Road, Worcester on Wednesday 2 January.
Police said a post-mortem examination found the cause of death was a stab wound to the torso.
A spokesman said a knife had been recovered from the property.
West Mercia Police said the man was arrested "in the early hours of this morning" and is being held at Worcester police station.
The 20-year-old man arrested on Friday has been charged with drugs and firearms offences and has been remanded into custody to appear at Worcester Crown Court on 8 April, police said.
Mr Locke's mother has appealed for the public to support the police's investigation.
Lilly Locke said: "Adie has sometimes been on the wrong side of the law, but he was a loveable rogue."
She described her son as "a real joker" and said that his family was "his life".
"He also had a teenage son, who he did not see much of as he grew up, but they had been getting to know each other recently - it's so sad that chance has now gone."
