AN investigation is underway after a human arm washed up on a south Dublin beach.
The grim discovery was made by gardai on patrol at Shankill Beach at midday yesterday.
The right arm has been taken to the city morgue in Marino for forensic examination.
It has not been identified, but is not linked to the discovery of a woman's leg last week.
The leg, which may have been severed by a passing ship in the bay, is understood to belong to a woman. It was found last Friday on a north Dublin beach.
Gardai are not treating the discovery as suspicious. It is understood gardai know the identity of the person.
In February last year, a human arm was found on the same beach. It was identified as belonging to a convicted rapist.
James Nolan (46), from Finglas, Dublin, had not been seen since his release from Portlaoise jail the previous November.
It is believed that he was murdered and his body cut into pieces and dumped in the Irish Sea. A suspect was identified by gardai and arrested in June of last year.
The suspect is a criminal who, like Nolan, has spent much of his life in jail for offences such as armed robbery, serious assaults and drug offences.
