"There is no active shooter threat at Central High School," said Av Harris, director of Legislative Affairs/Public Policy City of Bridgeport.

School Security, school resource officers, and school officials swept the building as a precaution.
To help give students a sense of calm, additional school resource officers will be stationed at the school for the day.
