More than 7,000 lines of inquiry are being followed, officers say
Gardaí have appealed for anyone who was at the Regency Airport Hotel when David Byrne was murdered to contact them with any footage of the incident.
Mr Byrne’s shooting at a boxing weigh-in on February 5th marked a major escalation in the Kinahan-Hutch feud.
Seven men have lost their lives since September in the escalating gangland dispute.
To date, gardaí have charged two people in connection with the shooting.
Officers say they are following more than 7,000 lines of inquiry.
David Byrne was shot dead in a packed room at the hotel, and there were hundreds of witnesses.
Superintendent Finbarr Murphy is appealing for any recordings they may have.
"We've got a huge amount of cooperation from the public and staff - we're looking for a little bit more if there's anything we haven't gathered so far," he said.
Gardai have thanked the communities affected by these brutal, high-profile murders for their help so far. And they’re assuring them they can come forward in confidence.
Deputy Commissioner John Twomey says the whole force is determined to end the feud.
