Sheriff's deputies Tuesday morning arrested a man they said turned himself in after calling authorities Monday about threats to Centennial Elementary School in Graham that appeared to be unfounded.
Pierce County Sheriff's spokesman Ed Troyer said Monday that a man called the Sheriff's Department and Tacoma police to say somebody was threatening a teacher on campus and later that a bomb was going to be there.
Troyer said Tuesday that the caller had turned himself in after seeing he was wanted on Facebook, and had been arrested but not made any statements.
Further details about the man and why he allegedly made the calls were not immediately available.
No threat was found on campus, Troyer said.
The school was on modified lockdown Monday as deputies investigated.
