Narrative:
Aircraft #2 was on final approach behind aircraft #1. I slowed aircraft #2 when he was approximately 4.2 miles behind aircraft #1 to final approach speed just outside final approach fix. The tower controller then cleared #2 to land and I immediately told aircraft #2 to go-around and climb and maintain 4000 ft. Although more than 4 miles existed before the go-around instruction as aircraft #2 was going around he may have been less than 4 miles while executing the missed approach. I reported this to the supervisor on duty at the time.
