A 54-year-old man remains in a serious condition after being shot a number of times.
David Douglas suffered several gunshot wounds when a car pulled up beside him on Killala Road, Cabra, Dublin 7, at about 7.30pm on Sunday night.
Local Fianna Fáil politician Mary Fitzpatrick has called for additional resources for gardaí following the shooting.
Mr Douglas is known to the gardaí and was sentenced in 2011 to 10 years in prison, with the last six suspended after he and three other men were apprehended in a car with cocaine valued at €2 million.
Detectives from the Garda National Drugs Unit arrested the men on April 13th, 2008, after a surveillance operation had been set up following a tip-off.
Convictions
Judge Tony Hunt sentenced Mr Douglas after he heard that he had several serious criminal convictions.
Mr Douglas is also a former keeper at Dublin Zoo.
Gardaí are treating the incident as attempted murder and witnesses are being asked to come forward.
A Garda spokesman said no arrests had been made yet and the man remains in a serious condition.
Gardaí in Finglas are appealing for witnesses or anyone who may have any information to contact them on 01-6667500, the Garda Confidential Line on 1800-666111 or any Garda station.
