The murder of a young man in Drimnagh in Dublin during the early hours of Monday is believed to have been the results of a feud between rival gangs.
Josh Itseli (20) was shot several times on Knocknarea Road shortly after midnight on Monday.
Two men in their 20s and a male teenager are being questioned after they were arrested by armed gardaí near the scene.
Gardaí confirmed that a post-mortem examination is due to be carried out on the victim's body on Tuesday.
The three arrested males remain in Garda custody, the Garda statement said, adding that a firearm has been recovered in the course of the investigation.
Gardaí believe the murder is linked to the organised crime scene in Dublin, and that the suspected explosive device was planted by one of the rival groups, as The Irish Times reports.
A number of cars have been seized as part of the investigation and a possible explosive device found nearby had to be made safe by the Army Explosive Ordnance Disposal (EOD) team.
All the scenes in the Drimnagh area which were sealed off for technical examination has since been lifted and roads have reopened.
In an update issued on Monday afternoon, Superintendent Paul Maher said: "An Garda Síochána are appealing for any person with CCTV footage in the wider area of Cooley Road, Brandon Road, Errigal Gardens, Crumlin Road, Slievenamon Road, Mourne Road and associated side roads and who were in the Knocknarea Road area between 11.30pm and 12.30pm last night to make any footage available to An Garda Síochána."
Commenting on the incident, Minister for Justice Helen McEntee told RTÉ: "The attack in Drimnagh last night was completely unacceptable and is not something we will tolerate on our streets.
"I commend the gardaí for responding quickly, resulting in the speedy arrest of suspects. Tackling crime and ensuring safer streets continues to be a top priority for An Garda Síochána and the Government."
Supt Maher confirmed a number of scenes, including the scene of the fatal shooting, remain sealed off while technical examinations take place.
A number of other vehicles on Knocknarea Road have been damaged and remain part of the technical examination, while a vehicle of interest, a silver Ford Focus, is being examined on Sperrin Road.
An investigation room has been established at Sundrive Road Garda station, and gardaí are appealing for witnesses or anyone with information to come forward.
Anyone with information is asked to contact Sundrive Road Garda station on 01-666 6600, the Garda Confidential Line on 1800-666 111 or any Garda station.
