Mr Walker (35), a father of two, was shot in the head in the yard of a pigeon club on Shelerin Road, Clonsilla about 6pm as he was delivering pigeons last Friday week.
The suspect was detained for a week under anti-gang legislation and gardaí from Blanchardstown went to court a number of times to extend his detention.
Detective Sergeant Tallon applied for the man to be remanded in custody and the Judge remanded him to appear again at Cloverhill District Court on June 26th.
The judge also ordered he receive medical attention and granted free legal aid
Two other men who were also arrested and questioned about the murder remain in garda custody.
