A teenager arrested in connection with a serious assault in Dublin has been released.

A man, in his early 30s, was attacked on Crane Lane in Dublin 2 early on Saturday morning.

He was stabbed by a number of youths who robbed his phone.

A taxi man assisted the injured man and took him to St James's Hospital.

A description of the teenagers was circulated to gardaí, and an arrest was made a short time later.

The phone was recovered when the arrest was made.

The detained teenager has since been released and a file is being prepared for the Director of Public Prosecutions (DPP).
