Two people were killed and six others were wounded in two shootings by a single gunman that took place among thousands of costumed revelers during a Halloween street celebration in downtown Orlando early Friday, authorities said. Officers responded to a report of shots fired in the city’s downtown bar and restaurant district shortly after 1 a.m. as costumed celebrants fled on foot. A second shooting minutes later happened within a short distance of officers and they quickly made an arrest, the city's police Chief Eric Smith said during a briefing Friday morning. The six wounded, who range in age from 19 to 39, were transported to a hospital for treatment and were in stable condition, Smith said. A 17-year-old male suspect was taken into custody, said Smith, who showed video from street security cameras and a police body camera showing the two shootings and the suspect's arrest at the second shooting location. After the first shooting, police used security video to put out a description of the suspect, but the second shooting happened near police and officers saw the attack, Smith said.
