A vehicle rammed into a crowd of people waiting to enter a nightclub along a busy boulevard in Los Angeles early on Saturday, injuring 30 people.

Victims were transported to local hospitals and trauma centres, according to Captain Adam Van Gerpen, public information officer for the Los Angeles City Fire Department. At least three were in critical condition after being injured along Santa Monica Boulevard in East Hollywood, the fire department said in a statement.

Van Gerpen said that a line of people were waiting to enter a nightclub when they were struck by a Nissan Versa that also hit a taco truck and valet stand. Paramedics discovered that one of the patients had a gunshot wound, Van Gerpen said. He said his identity was not yet known.

“This is under police investigation,” he said. “This will be a large investigation with the LAPD.” People inside the club came out to help before emergency crews arrived, he said, to help the victims.

“They were all standing in line going into a nightclub. There was a taco cart out there, so they were ... getting some food, waiting to go in. And there’s also a valet line there,” he said. “The valet podium was taken out, the taco truck was taken out, and then a large number of people were impacted by the vehicle.”
