DENVER -- Three Denver schools were placed on lockout on Wednesday morning for about 90 minutes after shots were fired during an attempted carjacking, the the Denver Police Department said.
The incident happened near West 32nd Avenue and Clay Street just after 9 a.m., police said. No injuries have been reported.
North High School, Valdez Elementary School and the Academy of Urban Learning were placed on lockout about 9:20 a.m., but it was lifted just after 11 a.m., a Denver Public Schools spokesman said.
Lockout means the doors to the school are locked and no one is allowed to enter or exit.
Police believe a black Kia was involved in an attempted carjacking in an alley east and south of North High School. It then ended up at 32nd and Clay where the shots were fired.
Police responded to a business there to investigate the gunfire.
Officials believed a group of four teenagers fired the shots, then took off before police could arrive. Police worked with the schools and it was determined none of them was under any threats.
Police do not believe the suspects are students at the high school. No suspect descriptions have been released.
