Gardaí in Co Clare have arrested a man in his 20s today in connection with the fatal shooting of Roy Collins in Limerick earlier this year.
The man was detained just before 9am in Meelick.
Roy Collins, a businessman and father-of-two, was shot dead at the Roxboro shopping centre in Limerick last April.
A 23-year-old man has already appeared in court charged with his murder.
