ORLANDO, Fla. (AP) — Officials searched Friday for a gunman who opened fire in a downtown office building where he used to work. At least six people were hurt.

People streamed out of the 16-story Legion Place office building around lunchtime and some told local television stations they had barricaded themselves inside their offices.

Orlando Fire Department District Chief Michael Droege said an unknown number of people were still in the building and could be injured. He said the SWAT team was trying to pull people out.

“The building is not secure now,” he said. “It’s still unfolding.”
