Gardaí investigating the murder of Christopher Warren have sealed off an area near the Broadstone bus station in Dublin.
The 35 year old, who was known to gardaí, was shot in the chest and dropped off at St James' Hospital in Dublin at around 7pm on Friday evening, where he subsequently died from his injuries.
Gardaí are appealing for anyone who may have seen a Blue Mercedes car which dropped Mr Warren off at the hospital to contact them.
The car was later found abandoned by gardaí on nearby Cork Street.
A man in his late 20s was yesterday arrested in connection with this murder, he is currently being questioned at Kevin Street.
