Detectives yesterday arrested a man on suspicion of murdering a Dundalk teenager, Ciara Breen, in 1997, but he was later released without charge. His arrest followed investigation by Dundalk detectives and by members of the Operation Trace team which was established to examine the disappearances of a number of women in the Leinster area.
Ms Breen, who was 17, has not been seen since the night of February 12th, 1997, when she left the terraced home she shared with her mother, Bernadette.
