A 911 call to police regarding an attempted burglary of an apartment has led to a standoff with an armed suspect in Chinatown. The Chronicle reports that the 900 block of Pacific Avenue is blocked off as hostage negotiators attempt to convince the suspect — now barricaded in the apartment — to surrender.

When police arrived at the scene of the reported crime, a single shot was reportedly fired by the suspect — although it is unclear if the shot was directed at police.

"The shot fired was not from the officer, it was from the suspect,” SFPD spokesperson Officer Grace Gatpandan told the paper. “So now were dealing with a hot prowl burglary with a suspect armed with a gun. This is a very dangerous situation and we’re advising everyone to stay away from the area.”

According to KRON4, no one was injured by the gunshot, and the suspect appears to be barricaded in the apartment alone — the resident was able to escape.

Update: According to the San Francisco Police Department, the suspect is in custody. There is no word yet on whether he (or she — at this time the gender is unknown) gave himself up, or if police were forced to raid the apartment.

Second Update: According to the Examiner, multiple officers were injured today in the process of taking the suspect into custody — although a police spokesperson declined to describe the nature of the injuries. The suspect was reportedly arrested just after 2:30 p.m., and was transported to a local hospital.

A police spokesperson on scene says six officers were injured with non life-threatening injuries.

Third Update: A police spokesperson has released the nature of the injuries. "Six #SFPD officers were slashed, bit and spat on by armed burglary suspect, who was taken into custody after being hit with bean bag rounds," writes a Chronicle reporter on the scene.
