Police investigating the murder of dissident republican Tommy Crossan have appealed for information about a red BMW car used in the shooting.
Crossan - a former chief of the Continuity IRA - was shot twice in the head and several times the body in the Good Friday gun attack in the Springfield Road area of west Belfast.
Tommy Crossan was buried on Thursday following scenes reminiscent of the darkest days of the Troubles, as masked men flanked the coffin of the 45-year-old.
Police now want to know the movements of a red BMW which was found burnt out.
It was discovered at nearby Beechmount Grove.
The officer leading the investigation, Detective Superintendent Jonathan Roberts, said the lead was "an important strand" in the investigation.
He said police wanted to track the car's whereabouts in a number of areas between 3.45pm and 5.15pm.
They include the Springfield Road, Springfield Avenue, The Peter Pan complex, Beechmount Crescent, Mica Street, Mica Drive and Beechmount Grove.
"We are also keen to speak to anyone who saw any person or persons coming out of an alleyway which runs between Beechmount Grove and the Mica Street/Mica Drive junction between 3.45pm and 5.15pm and whether they saw any person or persons get into a vehicle during this time," he said.
"We would also appeal to people in Beechmount Grove to tell us if they saw an old style red BMW coupe in the area prior to last Friday or if they saw the car being set on fire last Friday afternoon."
"The car was slightly unusual in that the shading of the red on the front offside quarter panel, bonnet and bumper appears to be slightly lighter than the rest of the car. We would also be interested in talking to anyone who saw the car in the area over recent weeks."
A 26-year-old man arrested in west Belfast by police investigating the murder was later released without charge.
