A second man is to be charged with the murder of Christopher Jackson, whose body was found in a wardrobe at the weekend.
The man, aged 35, will appear before Dublin District Court this morning, after being questioned by gardai about the killing over the past two days.
A woman in her 40s has been released without charge.
She was one of three suspects detained after gardai were alerted to the murder of Mr Jackson (53), who sustained multiple stab wounds.
Gardai found the body in the wardrobe of a flat at 82 Prussia Street in Dublin's north inner city on Saturday after receiving a tip-off. The corpse had been wrapped in a duvet and plastic bag.
Dublin District Court heard yesterday that Bernard Locke (39), of 82 Prussia Street, stated "no response" after being charged with Mr Jackson's murder at the same address.
Mr Locke, who has not indicated how he will plead, was remanded in custody and legal aid was granted after the court saw a statement of his means.
