NEW YORK (AP) - New York City prosecutors say they've filed murder charges against three people accused of taking part in an armed robbery that left a bodega worker shot dead by police.

The robbery occurred at a Bronx bodega early Friday. A worker frantically fled the shop with his head down and plowed into a police officer who had his gun drawn. The worker and the officer tumbled to the sidewalk, and the officer's gun went off.

Dramatic security video released by police shows a pool of blood forming on the ground.

Police call the shooting a tragic accident.

Police say one of the robbers quickly surrendered after the shooting and the two others were taken into custody later.

Prosecutors say the three men also face robbery and weapons possession charges.
