Miami-Dade police were investigating an officer-involved shooting Thursday after a man threw pieces of concrete at an officer trying to conduct a traffic stop.

Here is what Miami-Dade police spokesman Detective Roy Rutland said happened:

It started soon after a Miami-Dade officer pulled over a red Ford Focus for a traffic stop about 2:30 p.m. near Northwest 22nd Avenue and 56th Street.

While the officer was outside her vehicle, a man pushing a shopping cart down the street came up to her, yelling profanity. He pulled out a blanket with pieces of concrete inside, Rutland said, and began throwing concrete at her. One piece shattered a window of her cruiser.

The officer fired at the man, striking him in the lower extremities. He tried to run away but was soon caught by police. He was taken to Jackson Memorial Hospital, where he was expected to recover.

Rutland defended the officer’s decision to fire, pointing to the attack on Miami-Dade Detective Carlos Castillo in 2010 by a person who hurled a concrete cinder block onto Castillo’s head, then kicked the bloodied detective and stole his vehicle.

“We almost had a detective die years ago that was attacked with pieces of concrete,” Rutland said. “We don’t take these situations lightly.”

The driver who was pulled over for the traffic stop wasn’t hurt.

At the same time, a large crowd gathered to see what was happening, with some people in the crowd screaming profanities. One person had a dog that was acting aggressive, Rutland said, and police asked the owner to take away the dog.

The owner let go of the dog and it bit a detective who was trying to control the crowd.

The dog was shot and killed. The dog owner was taken into custody.
