Dallas police officials have issued an all-clear after searching for a suspicious person in a parking garage next to the department’s headquarters Saturday night.
The department says on Twitter that it searched the garage with officers and dogs to ensure a report of a suspicious person was thoroughly investigated.
At least two Dallas Police Department buildings were blocked off near the garage, with numerous police vehicles and armed officers outside. An armoured vehicle was moved to near the department’s downtown headquarters and heavily armed officers were seen walking nearby.

The police department also asked media not to broadcast live near the headquarters for the safety of officers. They say the headquarters building is not on lockdown and that no shots had been fired. They also say SWAT officers set off a device to enter a locked fence.
A nearby light rail station also was closed. The Dallas Transit agency cited “police activity.”
A Dallas police spokeswoman said earlier Saturday that the department received an anonymous threat against law enforcement across the city and has tightened security.
Other departments around the country have been receiving threats. They follow videos involving police shootings of black men in Louisiana and Mississippi, and the killing of five police officers by a sniper in Dallas.
