A man charged in connection with the detention of bulk cargo vessel MV Matthew is due to appear in court tomorrow morning.
The man is due to appear at a sitting of Wexford District Court at 10.30am.
Four people remain in garda custody as part of the investigation.
The Panamanian-registered ship, which left South America last month, was intercepted and escorted to port in Cork on Tuesday by an Irish joint task force which included gardaí, the naval service, army rangers and Revenue customs.
It is thought the ship was intending to rendezvous with a trawler which ran aground off the Wexford coast.
Two other men are before the courts in connection with the investigation.
