A man charged with possession of a pistol by detectives investigating the murder of a former IRA man remains a suspect in the killing, a court has heard.
Patrick Fitzpatrick (53) was remanded in custody at Lisburn Magistrates Court.
Father-of-nine Kevin Mc- Guigan was shot in east Belfast in a suspected feud between former IRA members last week.
Deputy district judge Philip Mateer heard that Mr Fitzpatrick, from the Lagmore Dale area of west Belfast, was suspected of involvement in the murder.
"He remains a suspect in the murder of Kevin McGuigan," said a detective.
The PSNI officer revealed that when police approached his house on Tuesday to make the arrest, the accused tried to escape out the back with a "sophisticated" Glock pistol and holster. He has been charged with possessing a firearm with intent to endanger life. His solicitor insisted his client only obtained the weapon to "protect his family".
Judge Mateer refused a bail application and Mr Fitzpatrick was remanded in custody to appear before the same court, via video link, next month.
