ORLANDO, Fla. – Police Chief John Mina said Friday that Orlando police received a "vague threat" in the wake of the Dallas shooting that left five officers dead and seven others injured, but he didn't provide any specifics.
Mina made the comment at a news conference about the Dallas shooting, which came almost one month after 49 people were killed and 53 others were injured in a mass shooting at an Orlando nightclub.
"For officer safety reasons, we won't give specifics about threats received after #DallasPoliceShooting," Orlando police tweeted. "OPD is vigilant and investigating."

"All of our officers know about this vague threat, and we will bring those people to justice if there are charges developed because of that threat," Mina said. "Just like here in Orlando, Dallas will receive support not only law enforcement from across the world, but they'll receive support from communities across the world."
A suspect who died in a standoff with Dallas police said he wanted to kill white people -- especially white officers -- and that he was upset about "the recent police shootings," and that he acted alone, Dallas Police Chief David Brown told reporters Friday.
Five police officers were killed and seven others were injured in the ambush in Dallas that began Thursday night, officials have said, in the deadliest single incident for U.S. law enforcement since September 11, 2001. Two civilians also were injured in the shootings, the office of Dallas' mayor has said.
Most of the injured Dallas police officers have been released from a hospital, Brown told reporters. The officers' conditions are improving, Brown said.
"All I know is that this must stop -- this divisiveness between our police and our citizens," Brown said. "We don't feel much support most days. Let's not make today most days. Please, we need your support to be able to protect you from men like these, who carried out this tragic, tragic event."
Brown said an investigation into the ambush continues.
