(CNN)A Christmas morning explosion that rocked downtown Nashville, injuring at least three people and damaging dozens of buildings, is believed to be an intentional act, authorities said.
Officers with the Metro Nashville Police Department were responding to a call of shots fired Friday morning when they came upon an RV parked in front of an AT&T building at 166 2nd Avenue North, according to police spokesman Don Aaron. Police saw no immediate evidence of shots fired, Aaron said in a news conference, but something about the RV prompted the officers to request the department’s hazardous devices unit. The bomb squad was responding to the downtown area when the RV exploded at 6:30 a.m. CT, Aaron said. “We do believe this to have been an intentional act,” Aaron said. “Significant damage has been done to the infrastructure there on 2nd Avenue North.” Read MoreThree people were transported to hospitals from the scene, but none were in critical condition, according to Nashville Fire spokesman Joseph Pleasant.The force of the explosion knocked down one officer, Aaron said, and caused hearing loss in another — hopefully temporarily, he said.

He got up and looked out the window, he said, but went back to bed when he didn’t see anything.Asked if the noise he heard could have been something other than gunfire, McCoy emphasized that he believed it was, saying he owns a gun and goes shooting, so he’s familiar with the sound of gunshots.Emergency personnel work at the scene of the explosion.Investigators are doing a secondary search of buildings downtown, particularly those on 2nd Avenue, to make sure no one is in need of help, Aaron said. Prior to the explosion, officers had gone door-to-door or apartment-to-apartment to inform residents of the situation. One man walking a dog on 2nd Avenue was redirected by an officer just before the RV exploded, he said. Officials do not know whether anyone was inside the vehicle when the explosion occurred, he said. Police are not aware of any other attempted explosions. Nashville Mayor John Cooper told CNN that dozens of buildings have been damaged, mostly from having glass blown out. Some buildings have been evacuated, the mayor said, but he did not know how many buildings or how many people had been impacted.”Right now, there’s just a whole lot of glass damage on 2nd Avenue,” he said.
