Two students were injured and a female suspect is in police custody following a shooting at a Los Angeles school on Thursday, police told media.
The Los Angeles Fire Department said a 15-year-old boy who was wounded is in critical condition.
A 15-year-old girl with a gunshot wound to the wrist was taken to a hospital in fair condition, Scott said.
"We know this a very traumatic incident for all the children involved, particularly inside that classroom", said Steven Zipperman, chief of the Los Angeles school system police department.
"The school has been declared safe at this point".
One parent told ABC Los Angeles station KABC-TV that the shooting took place next to her son's classroom.
A gun was recovered from the scene, police said.
"I'm just hoping it has nothing to do with him", she said.
The middle school is located on the same campus. "I said 'No.' Then I moved away from her because I was a little bit scared".
Anzueto said there were no metal detectors at the school.
The location initially was reported as Belmont High School. Officials have not said whether students at the school were subject to any weapons screening Thursday. A 30-year-old woman who was treated after the shooting was not hospitalized and the nature of her injury was not immediately known. The school has about 365 students in grades 6-8 and nearly all are Hispanic and many are from low-income families.
