A large law enforcement presence along Murray Drive and near Hanahan High School on Wednesday morning was in response to a threat reportedly made against the school, according to Berkeley County School District officials.
BCSD staff said on the district's social media accounts Wednesday morning threats against the school had been received by the Berkeley County Sheriff's Office and the Hanahan transportation office.
Officials later confirmed that the threat was a hoax after a search of the campus and nearby areas.
All students who were on campus Wednesday morning are safe, according to Hanahan Police.
School district officials said they never believed the threat was credible, but took them seriously.
Hanahan High School opened on a 2-hour delay in response to the incident, according to the school district. Students were not allowed on campus before 10:15 a.m.
Law enforcement and district safety and security personnel are investigating the incident, according to BCSD officials. On Wednesday night, officials confirmed that the FBI was investigating as well.
Hanahan Police said Murray Drive from Belvedere Drive to Smithfield Place was closed for police activity.
The North Charleston Police Department and the Goose Creek Police Department also sent officers to patrol Hanahan Elementary School, Hanahan Middle School, and Bowen's Corner Elementary School out of precaution.
Authorities said additional information will be released as the investigation continues.
