ATLANTA — FBI Atlanta officials say three drones were seized after operators violated temporary flight restrictions put in place around FIFA World Cup-related events in metro Atlanta.

According to the FBI, the drones were confiscated Thursday after operators flew in restricted airspace established ahead of World Cup activities in the city.

Special Agent in Charge Marlo Graham said the restrictions are intended to protect public safety.

“The government can establish temporary flight restrictions around special events to keep the public safe,” Graham said.

Graham warned that violating those restrictions can result in significant penalties.

“Violations can result in criminal fines up to $100,000, one year in prison, and seizure of your drone,” Graham said.

The FBI said drone operators who violate the restrictions could face criminal charges in addition to having their drones confiscated.

“Flying in those areas isn’t just dangerous, it’s a federal crime,” Graham said.

Officials are urging drone operators to check flight restrictions before taking off.

Graham said operators can use the FBI’s “Before You Fly” app to determine where restrictions are in place before operating a drone.

Authorities say improper or unsafe drone use can pose hazards to aircraft and people on the ground and may violate federal law.
