TOLEDO, Ohio (AP) — An Ohio man is accused of making an online threat to shoot up an Illinois village and causing a panic that prompted school lockdowns.

Federal authorities say a 22-year-old man from the Toledo area made the threat about Shorewood, Illinois, two weeks ago in an online chat where users can talk anonymously.

Prosecutors say it caused schools to cancel outdoor recess, hire extra security and go into lockdowns. Police in Shorewood say they were overwhelmed with calls from concerned residents.

The man, Ryan Gagnet, of Maumee, is charged with a related count in federal court. A message seeking comment was left with his attorney.
