Police say tips led them to the teenager, who was arrested from his home in south Roswell.
A teenage boy has been arrested in the theft of a fiberglass and metal version of a spaceship from outside the UFO Museum in Roswell.
Police say they're still searching for two other suspects.
The model spaceship has been a fixture in downtown Roswell, where it was long mounted outside the UFO museum before a recent snowstorm damaged it.
It was being stored behind the museum before it was stolen March 19.
Police say surveillance video showed three people hauling the spaceship off in a pickup truck.
The saucer was found in pieces two miles west of Roswell last Wednesday.
Police say tips led them to the teenager, who was arrested Saturday at his home in south Roswell. His name wasn't being released.
Roswell still stirs debate about extraterrestrials seven decades after the 1947 crash of a flying object.
