Detectives investigating the murder of a 20-year-old have arrested a man.
Dean Johnston was shot dead as he sat in the back of a car outside the home of his best friend in Moorefield Avenue in Neilstown, west Dublin, on May 25 last year.
Investigating gardai said they arrested a 23-year-old man in Co Wexford on Monday night.
A Garda spokesman said: "He is being detained at Lucan Garda Station under the provisions of Section 50 of the Criminal Justice Act 2007."
Mr Johnston was killed when a man walked up to his friend's VW Golf car and fired five shots from a handgun into a rear passenger window.
He was hit in the head and shoulder and was later pronounced dead at Tallaght Hospital.
Mr Johnston lived a few doors away from where the shooting happened.
