The man was detained in the west Belfast area on Friday night.
He is being questioned by detectives from the PSNI Serious Crime Branch in Antrim.
The incident happened at Golf Madness in Cornmarket at about 6.40pm on Monday.
Eyewitnesses described how the suspected bomber ran from the building with his coat on fire before abandoning an incendiary device in the street and fleeing through crowds of shoppers.
Police sealed off part of city centre in the wake of the attack, which came just days after a device containing flammable liquid exploded outside a restaurant in Cathedral Quarter.
They said they believe the man suffered burns to his face, neck and hands after the device went off prematurely.
None of the people who were inside the pop-up golf store were injured when the device went off inside the man's jacket.
Police have advised city centre businesses to check their premises for any suspicious objects after the latest terrorist incident linked to dissident republican activity in the city.
Anyone with information is also asked to contact the PSNI.
