Two teenagers were shot Friday morning at a high school in Glendale, Arizona, prompting authorities to lock down the building as they investigated, police said.

“It’s been stabilized, and students are not in (further) danger,” Glendale police Officer Tracey Breeden told reporters about the shooting at Independence High School.

Details about the teens’ identities, their conditions, and whether police had anyone in custody weren’t immediately available.

The shooting happened at a covered patio area near the main building before 8 a.m., Breeden said.

Breeden said she didn’t know whether the teens who were shot were students at the school.

“The incident was isolated. The school and neighborhood are safe,” Glendale police said on Twitter.

Police asked students’ parents to gather at a nearby Walmart to await further information. Video from CNN affiliate KNXV-TV showed scores of people gathered in the store’s parking lot as well more standing across the street.

“Our prayers are with the students, educators & families at Independence High School & all the first responders on the scene,” read a post on Arizona Gov. Doug Ducey’s Twitter account.

Independence High School opened in 1977 and is part of the Glendale Union High School District. More than 2,000 students are enrolled.

Glendale is a city of about 230,000 just northwest of Phoenix.
