He has been taken to Musgrave Serious Crime Suite in Belfast for questioning.
A PSNI spokesperson said a property was also searched and a number of items have been taken away for further examination.
Mr Caldwell was shot several times in front of his son at a sports complex in Omagh, Co Tyrone, in February.
The detective, who had investigated a number of high-profile murder cases, spent several weeks in intensive care.
A typed message, purportedly from the New IRA, was posted on a wall in Londonderry and said the group was responsible for the shooting.
Police have said the New IRA is the main line of inquiry in the investigation.
A number of people have previously appeared in court charged in connection with Mr Caldwell’s attempted murder and on charges around the claim of responsibility.
