MIAMI (AP) - Detectives are investigating after a Miami-Dade police officer shot and injured a pedestrian who started tossing pieces of concrete during a traffic stop.
    
Police say a patrol officer was involved in the routine traffic stop Thursday night when a man pushing a shopping cart along the road started threw several large pieces of concrete, striking her cruiser.
    
According to police, the officer shot the man in the leg. He was treated at a hospital and released back into police custody.
    
After the shooting, police say a large crowd gathered and began screaming obscenities at the officer. When additional officers arrived, someone in the crowd released a dog, which attacked an officer and bit him in the abdomen. Officers shot and killed the dog and the owner is in police custody.
