San Jose officers were called Saturday night to investigate the stabbing of two teenagers at Eastridge Mall and were looking for three male suspects, police said.

Officer Jose Garcia said both teens suffered life-threatening injuries and were taken by ambulance to a local hospital.

Investigators closed and evacuated the JC Penney and Macy’s department stores, in addition to a portion of the mall, shortly after receiving a 911 call about 7:30 p.m. so that police could process the crime scene.

Officers found both teens at the mall suffering from at least one stab wound each.

Witnesses said that they saw three men attacking the teens. Police had three young men detained at the mall, but Garcia said that police don’t know for sure if they are the attackers. They are asking for the public’s help with any information about the crime.

Garcia said the motive was unknown and remains under investigation. Anyone with information about the incident is urged to call the San Jose Police Department at 408-277-8900.
