DALLAS (Reuters) - A busy section of downtown Dallas near major businesses was shut to traffic on Tuesday and several buildings were placed on lockdown after a man with a gun barricaded himself in an apartment, police said.

At least one shot has been fired through a window by the man, thought to be in his mid-40s and facing eviction. No injuries have been reported, police said.

A police SWAT team has "set off a flash bang as a distraction device," the Dallas Police Department said on Twitter.

"SWAT right now has the situation contained," a Dallas police spokesman told reporters, without offering further details.

The apartment is in an area known as Victory Park, about 1,200 feet south of the American Airlines Center home of the NBA's Dallas Mavericks and the NHL's Dallas Stars.

Police have set up barricades and said they have placed the W Hotel, Perot Museum, the Dallas World Aquarium, a local high school and other buildings on lockdown. They have also cleared pedestrians from the street who could be in the suspect's line of fire.
