DALLAS — Dallas police were in a standoff early Saturday morning after suspects in an armored van opened fire on the department’s headquarters before leading officers on a chase to Hutchins, about 10 miles southeast.

At 5:40 a.m., police said the suspects’ vehicle had been “disabled” with a .50 caliber rifle, but a standoff continued.

The South Side on Lamar apartment complex in the 1400 block of South Lamar was evacuated as a precaution after one or more bombs were discovered outside police headquarters.

Just after 6 a.m., Dallas Police Maj. Max Geron said on Twitter that officers were clearing the station.

“Not ‘evacuating’ but getting officers to clear in service from the station,” he said in response to a tweet.
