Gardaí have established the identity of a 24-year-old man killed today in what is believed to have been a case of mistaken identity in a gang-related murder in Dublin.

It is understood the victim was for a time homeless but more recently lived in the north inner city with his partner.

It is understood he was the father of several children and was known to gardaí for a number of previous offenses including burglary, theft and drugs. 

Gardaí do not believe that he was involved in the gang-related feud or in organised crime. 

The shooting happened outside a pub near Sheriff St and Oriel St at around 12.30pm.

As many as six shots were fired.

Gardaí say the gunman escaped on a bicycle which he abandoned nearby, they say he was dressed in black, and had a scarf covering his face.

The victim was taken to the Mater Hospital but pronounced dead there an hour later.

A handgun which was recovered from a wheelie bin near the scene this afternoon is being examined to establish if it is the murder weapon. 

Gardaí also say the victim, was seen running shortly before he was shot.

It is the fifth murder as part of a feud between associates of Gary Hutch, who was shot dead in Spain last year, and David Byrne, who was connected to the Kinahan international drugs cartel based in Spain.
