Chief John DeCando, spokesman for Paterson Police's animal control division, says the bull was being unloaded at ENA Meat Packing Inc. when it broke loose just before 8:30 a.m. Monday.
Police tried to corral the bull by lassoing a rope around the animal's neck, but it dragged officers down the street instead.
DeCando says traffic was light during the bull run. He says the area where the officers were dragged was not residential or near a school.
Officers finally corralled the animal and DeCando was able to sedate it.
No injuries were reported. The bull was returned to the slaughterhouse.
