CHESAPEAKE, Va. (WVEC) -- A 16-year-old Great Bridge High School student who allegedly made inappropriate posts on social media is facing numerous charges from Chesapeake Police and the Chesapeake Fire Department.

On Sunday, School Resource Officers were notified of the posts, and several additional units were requested to patrol the area on Monday.

Chesapeake Police said the school looked internally into the matter as well, and took appropriate action.

During the on-going investigation, police discovered other videos the student made. As a result, the student in question was charged with two misdemeanor counts Underage Possession of a Firearm and Discharging a Firearm within City Limits.

The offenses occurred Sunday in the 200 block of Golden Maple Drive.

Chesapeake Fire also said they have charged the student with four unrelated felony charges stemming from separate incidents: in one, the student was seen on video with two other juveniles throwing a Molotov cocktail in the Great Bridge High School parking lot.

The student was also charged in relation to throwing a fire bomb at a port-a-potty at a construction site off of Hanbury Road.

All three juveniles in the first video are charged with felony counts of manufacture, possession, or use of fire bombs or explosive materials or devices, and conspiring to commit a felony. The student is also charged with two felony counts of burning or destroying personal property.

Police said the student is currently being held in Chesapeake Juvenile Services.

The social media posts had many parents and students concerned with their safety. One parent described the student's social media postings as "pictures of himself and video stating that he was going to shoot up the school. He had a gun in his hand in one picture."

On Tuesday, Great Bridge Principal Jeffrey Johnson sent a letter home to parents saying "never was there a threat within our school building," but a Parent Alert call was issued to inform parents they were aware of the social media postings.

The principal said police were involved in an active investigation and that, "any student identified by authorities as being involved has not been allowed to come back to the school."
