A man arrested in connection with the murder of a former dissident republican has been released by police.
The 24-year-old was freed unconditionally, a Police Service of Northern Ireland (PSNI) spokeswoman said.
Tommy Crossan was shot dead as he sat in a hut at a fuel business off Springfield Road in west Belfast.
It is believed the 43-year-old had been expelled from the anti-peace process Continuity IRA after falling out with other dissidents.
The killing was condemned by Northern Ireland's First and Deputy First Ministers.
