CLARKSVILLE, Md. — A bomb threat called into River Hill High School during dismissal time Tuesday was a hoax, according to Howard County Police.
The threat sent the school into lockdown, preventing students from going home on time.
Police say they detained a few students during their initial investigation, but all were released when it turned out they weren't involved in making the threat.
