The Garda Commissioner has said they are considering terrorism as one of many lines of inquiry following two fatal shootings in Dublin.

Noirin O’Sullivan has said the force is keeping an open mind – in the investigations into the murders of David Byrne and Eddie Hutch Senior over the last week.

An armed Garda presence is expected to remain in place around the city in the coming days – while officers are renewing their appeals for information in relation to both killings.

Commissioner O’Sullivan has said all options are being considered: “I think that it is very important that we keep an open mind.

“But certainly we are looking at crime and terrorism, we can rule nothing out at this stage.

“We are keeping a very open mind, but what is very clear it the people that are involved in both of these crimes, they are criminals.”

Meanwhile residents living near the scene of Monday night’s fatal gangland shooting have been calling for an armed garda response.

There was a heavy garda presence in the city last night after two recent gangland killings.

Investigations are continuing into the murders of Eddie Hutch Sr and David Byrne – no arrests have so far been made.
