ST. PAUL, Minn. (AP) _ Police have arrested a man suspected of sexually assaulting a 5-year-old girl waiting for her school bus in St. Paul in 2016.

Reports say investigators collected DNA evidence at the time of the assault but periodic database searches didn't turn up any matches until this past December.

The match led police to a 19-year-old man. Officers arrested him in Cahokia Heights, Illinois, on Monday. He is awaiting extradition to Minnesota.

The man would have been 13 at the time of the assault.
