Police arrested a 25-year-old man on Monday accused of breaking into a home on Arizona State University's Polytechnic Campus and robbing the victims inside.
Daniel Molina was arrested on Monday at his Mesa home and booked into jail on charges of robbery, burglary, kidnapping, endangerment and disorderly conduct.
Arizona State University Police said Molina broke into a unit at the West Desert Village, a shared housing complex on campus, on July 10, brandished a gun and demanded electronics from the people inside and ran away.
One of the victim's cell phones later pinged that it was in central Mesa.
Officers from ASU, Tempe, Scottsdale and Mesa worked together to locate the cell phone, conduct surveillance on Molina's home, arrest him and get a search warrant.
Police said they found the victims' stolen items inside Molina's apartment as well as a handgun.
Two other people inside Molina's apartment were arrested on unrelated charges, including drug paraphernalia and an outstanding warrant. They were not identified.
ASU police could not comment on Molina's relationship to the victims, but did say he is not affiliated with the University.
