Police say a threat to a high school outside Atlanta prompted a lockdown but no students were hurt.
Cobb County police said Monday afternoon that two people have been detained, and that no students have been injured.
Cobb County police Officer Sarah O'Hara told WSB-TV that a threat was made "via walkie-talkie." O'Hara said she didn't have any further information on the suspects who were detained.
Cobb County school district spokeswoman Nan Kiel said in a statement that "a rumored threat" was made on campus.
County police said they were assisting Smyrna police and campus police at Campbell High School, where parents were meeting their children at a nearby soccer field.
Smyrna is about 12 miles (19 kilometers) northwest of downtown Atlanta.
