Forensic investigators are at work outside a city centre nightclub after weapons were found outside last night.
At one o'clock this morning, a large gang of youths gathered in Adam Court, which leads off Grafton Street towards a club.
They left -- but afterwards, gardaí found a number of offensive weapons in the laneway.
The scene was been sealed off this afternoon as forensic investigators examined the area.
A man in his early 20s was arrested and charged in relation to last night's incident.
Gardaí say investigations are ongoing.
