A 28-year-old man was arrested today in connection with the discovery of the body in a Romanian in a suitcase in canal in Dublin, gardai said.
Two teenage boys made the grisly find on July 20 when they spotted a black nylon suitcase in the Royal Canal in the Irish capital.
The remains were later identified as those of Adrian Bestea, 21, and a post mortem examination showed that he died of head injuries.
A suspect, a Ukrainian man, was arrested in connection Mr Bestea’s murder at about 8am in the north city area.
He was being held at Mountjoy Garda Station.
Police can detain him for up to 12 hours before he must be released or charged.
Mr Bestea arrived in Ireland by boat at Rosslare two years ago, an initially stayed in County Wexford before moving to Dublin, where he worked on building sites.
A police investigation launched when his body was found failed to identify him for a fortnight, although it involved a check of dental records and assistance from Interpol.
Mr Bestea was finally named and his family in Romania contacted after detectives took the unusual step of publicising a picture of the dead man’s face.
Gardai have searched Mr Bestea’s last known address in the north inner area of Dublin, and have appealed to his friends, including a Russian body-builder thought to have been his girlfriend, to come forward.
