Police headquarters in Charlotte-Mecklenburg, North Carolina, have been evacuated due to a possible bomb threat. A bomb squad has been requested at the scene as authorities investigate a suspicious package.

Capt. Mike Campagna held a press conference where he explained that an employee working in the mailroom came across the suspicious package and alerted her supervisors. A canine bomb dog alerted its authorities that the package needed further investigation. It has since been removed from the police department and taken to a secure location where it can be assessed. Everyone was reported to be safe following the evacuation.

Campagna told reporters that this was the first time he knew of that the department has been evacuated due to a threat.

Tensions between the Charlotte-Mecklenburg Police Department and the public have been on the rise, with a week of protests having taken place over the high-profile shooting of Keith Lamont Scott. While the demonstrations were largely peaceful, skirmishes between police and protesters broke out and some officers were injured. Additionally, one protester was killed at Wednesday's demonstration and another attendee was arrested in relation to his death.
