Students at New Prague Middle School were evacuated for about an hour Thursday morning after several staff members received a bomb threat via email.
Students are now back in class.
New Prague's superintendent says administrators knew the latest threat was likely a hoax, but the school takes each threat seriously.
The threat came a day after the school was put into a Code Red lockdown after police say a 12-year-old student phoned 911 and falsely claimed there had been a shooting. The boy is now in custody awaiting a juvenile hearing.
