Six young people were shot after they stepped off a bus that had left a high school, leaving at least one critical, in a horror attack just streets from two primary schools.
Gunshots tore through the working-class neighbourhood in north-east Las Vegas just before 2pm local time yesterday (10pm Irish time), Officer Bill Cassell said.
Police were not saying whether the suspects were on foot or in a vehicle, but at least two people are believed to have taken part, he said.
Officer Cassell said the police gang unit was investigating, though it was not clear whether gangs were involved.
One of the victims, a man, was in a critical condition and a teenage boy was in a serious condition, University Medical Centre spokeswoman Cheryl Persinger said.
Four people had minor gunshot injuries to their arms and legs, including a man who was released. Three teenagers – two boys and a girl – were in a good condition, she said.
The school bus had left from Mojave High School, Clark County School District spokesman Michael Rodriguez said. The school was expected to open today with extra security measures and support services.
The shooting occurred a couple of blocks from two elementary schools. Mr Rodriguez said both were locked down temporarily but were later reopened.
Mojave had some 2,300 students last year, about evenly divided among blacks, whites and Hispanics, according to district materials.
Archie Gorai, 22, who lives about a block from the site of the shooting, said he heard about eight gunshots while he was wrapping Christmas presents at his home.
“I told my wife it was gunshots. She thought it was firecrackers,” he said.
The gun attack came after a fight over a girl at a high school, authorities said.
School police arrested three teenagers over the fight hours before the shooting, Sheriff Doug Gillespie said. Investigators were still seeking the gunmen.
