Miami Beach residents scrambled to safety Friday afternoon when police reported that a 911 caller warned there were two men on the rooftop of a building wielding a shotgun.
Shortly after 2 p.m., police took up positions and closed off Washington and Collins avenues between 11th and 12th streets.
About an hour later after detaining four men from a unit in the Del Rio apartment building at 11th and Collins, the streets were reopened. Police, searching the building, found a long assault rifle and ammunition in one of the units with the four men.
“Four subjects detained as we continue to investigate,” the Miami Beach police department tweeted.
Never miss a local story.
The four men, who haven’t been named, were still in custody and being questioned late Friday afternoon. By then, vehicle and pedestrian traffic had returned to normal.
