ATLANTA — Frightening moments unfolded for parents and students at Booker T. Washington High School as Atlanta police interrupted a homecoming event while searching for a suspected shooter nearby.

The incident began after shots were fired at a Texaco gas station at the corner of Martin Luther King Jr. Drive and Joseph E. Lowery Boulevard, just around the corner from the high school and near the Ashby MARTA station.

Police armed with long guns entered the school’s gymnasium during the homecoming coronation and instructed everyone to shelter in locked classrooms. Officers then canvassed the campus and eventually gave the all-clear, allowing the event to resume.

Outside, however, heavy police activity continued. SWAT units later focused their search on a home along Newcastle Street before concluding operations.

Authorities have not said whether anyone was taken into custody, and police are releasing few details about the investigation. Officials confirmed that no one was injured in the shooting.

Police K-9’s are also being used during the search to track down the suspect who was believed to be wearing black pants, and a red hoodie.

This is a developing story.
