Police investigating the murder of Gerard 'Jock' Davison in Belfast have made a second arrest.
The former senior IRA figure, who was 47, was shot dead as he walked to work in the Markets area of city on Tuesday morning.
A 27-year-old man was arrested on Wednesday evening in Belfast and is being questioned about the shooting.
A 41-year-old man, who was detained earlier on Wednesday, has been released unconditionally.
Police searched a property in north Belfast on Tuesday night as part of the overall investigation.
Police do not believe dissident republicans were behind the attack.
Appealing for information, Det Ch Insp Justyn Galloway said: "This was a cold-blooded murder carried out in broad daylight in a residential area and it has no place in the new Northern Ireland."
"We have detectives in the Markets area making house to house enquiries and seeking to identify witnesses.
"I would appeal to local people to co-operate with them and give them any information they have."
