The Metro Nashville Police Department released a photo of the RV that exploded in downtown Nashville, Tennessee, on Friday morning, Christmas Day.
The image appears to have been taken from a surveillance camera located at the intersection of Commerce Street and 2nd Avenue North, about half a block from the place where the incident happened.
The police said it arrived at 1:22 a.m. CT, about five hours ahead of the explosion.
The Federal Aviation Administration (FAA) temporarily halted flights out of Nashville International Airport (BNA), located 6 miles Southeast of the explosion site.
The explosion shook the largely deserted streets of downtown Nashville early Christmas morning, shattering windows, damaging buildings, and wounding three people. Authorities said they believed the blast was intentional.
Nashville police were able to usher people to safety before the explosion. A warning message was broadcast urging people to evacuate moments before the blast.
Officers with the Metro Nashville Police Department carried out door-to-door and apartment-to-apartment checks and managed to get people to safety shortly before the blast, according to statements made at a press conference.
There was a loudspeaker warning people to clear the area before the massive blast, according to a Metro Nashville Police spokesperson and surveillance footage.
“All buildings in this area must be evacuated now,” a voice could be heard in the video. “If you can hear this message, evacuate now,” the warning was repeated before the blast occurred.
One officer was knocked down to the ground by the explosion, while another experienced temporary hearing loss, police said at the presser. No officer sustained serious injuries in the incident, police said.
Police spokesman Don Aaron said three people were taken to area hospitals for treatment, although none were in critical condition.
He added that the 6:30 a.m. blast was believed to be “an intentional act.”
