Two murder investigations are under way in Sligo in the Republic of Ireland after the bodies of two men were found at separate addresses since Monday.
The body of a man in his 50s was found in an apartment on Connaughton Road on Tuesday night.
The previous night, 41-year-old Aidan Moffitt was found dead in a house at Cartron Heights.
An Garda Síochána (Irish police) said they could not comment on whether they suspect any link between the deaths.
Both victims sustained “significant physical injuries”, according to Gardaí.
Tánaiste (Irish Deputy Prime Minister) Leo Varadkar has said he was “shocked and “worried” by the killings.
Local officers investigating the Connaughton Road murder arrested a man in his early 20s in Sligo at 01:45 local time on Wednesday.
The arrest operation was supported by the Armed Support Unit and the suspect remains in custody in Sligo Garda Station.
The body of the victim, who has not yet been named, was reportedly found by relatives, according to Irish broadcaster RTÉ.
Gardaí were called to the scene at about 22:.30 local time on Tuesday.
Post-mortem examinations are being carried out on both bodies.
Detectives investigating Mr Moffitt’s death said they were trying to find out if he met his attacker online.
They said they were also investigating whether or not there there was a hate-related motive to the killing.
In their appeal for information on Tuesday, Gardaí also issued safety advice to members of the public who plan to meet people they have made contact with online.
They advised people to arrange meetings in public places and to use live video calls to confirm the persons’ identity before meeting them.
Mr Moffitt was a member of the Fine Gael party, which is led by Mr Varadkar.
He was originally from Roscommon and had been appointed as a branch secretary and branch chairperson of Fine Gael.
