Confederate flags have been found outside Atlanta’s Ebenezer Baptist Church near the Martin Luther King Jr. Center.
Atlanta police and the FBI are now looking for two white men who were spotted laying the flags on the ground in surveillance footage.
Police said a maintenance worker discovered the flags at 6 a.m. on Thursday and notified the National Park Service, which operates The King Center.
The church's reverend said grounds men were upset by the discovery of the flags.
A security guard told police he saw a suspicious vehicle across the street from the church on Wednesday.
Authorities are now looking into whether any specific threats were received, The Associated Press reported.
The discovery comes on the heels of the massacre at the Emanuel African Methodist Episcopal Church, an historic African-American church in Charleston, South Carolina, in June.
The Confederate flag was displayed by accused shooter Dylann Roof, who allegedly shot dead nine people inside the church.
Furor over the flag spread across the nation.
South Carolina Rep. Jenny Horne made an impassioned speech advocating the flag’s removal. After the Charleston shooting, South Carolina made a historic decision to remove the flag from capitol grounds.
Warner Brothers dropped sales of the Dukes of Hazzard car with the Confederate flag, and one journalist argued that the film, Gone with the Wind, should go away along with the flag. Politicians, pundits, and protesters across the nation have engaged in heated debates over the flag.
