Four quizzed over drug dealer's death

One woman and three men were being questioned today about the murder of a suspected major drug dealer.

They were arrested last night over the shooting of father-of-three John Carroll in Grumpy Jack's pub in south inner city Dublin.

The three men, all in their 20s and from the Crumlin area, were arrested at Dublin Port shortly before 8pm.

They are being detained under Section 30 of the Offences Against The State Act at Pearse Street, Kilmainham and Harcourt Terrace Garda Stations.

The woman, aged 30, who was arrested at her home shortly after 6pm, is being held under the same laws at Kevin Street Garda Station.

All four can be detained for up to 72 hours.

Detectives knew Carroll as an associate of a number of criminal gangs in the capital involved in drug trafficking, particularly a faction in Crumlin.

The 33-year-old was killed when a gunman wearing a motorcycle helmet burst into the bar, in the Coombe, on Wednesday night, singled out his victim and opened fire a number of times with a handgun.

The attacker made off on a waiting motorbike, along with an accomplice.

There were up to 20 people in the pub at the time of the shooting.

Drugs detectives believed he was behind the large-scale distribution of cannabis, ecstasy and cocaine, shifting as much as hundreds of thousands of euro worth of drugs every month.
