A man in his 20s has been arrested in connection with the murder of a 90-year-old man in Co Waterford at the weekend.

The body of Paddy Lyons was discovered at his home in Ballysaggart near Lismore, Co Waterford on Saturday.

The discovery was made by a neighbour who also acted as a home help for Mr Lyons.

It is believed Mr Lyons had a number of marks on his body, which led gardaí to seek a full post-mortem examination.

Supt Michael Lacey, who is leading the murder investigation, has appealed to witnesses to come forward.

A couple that gardaí had been seeking to speak to earlier have come forward and have been eliminated from the inquiry.

Supt Lacey said Mr Lyons was last seen alive on Friday evening, 24 February.

Post-mortem details will not be released for operational reasons.

Supt Lacey also said the scene is still being examined.

Anyone with information on the incident should call the incident room in Dungarvan on 058-48600 or the Garda Confidential Line 1800-666-111.
