SAN ANTONIO -- Navarro Academy was placed on lockdown on Tuesday after police and school officials say a student was stabbed and the suspect fled campus.
A spokeswoman with the San Antonio Independent School District said police were searching for the 19-year-old suspect near the parking area.
San Antonio police said they were first alerted after a student walked into the nurses office at the Navarro Academy, 623 Pecos La Trinidad, complaining of a stab wound to the back.
SAISD spokeswoman Leslie Price described the injury as "puncture wounds from a sharp object."
She said the injured student was transported to University Hospital.
School officials said the school went into lockdown as a means of containing the campus environment during the lunch hour.
The University of Texas at San Antonio sent out two messages on its emergency alert system in regards to the stabbing because of the proximity of Navarro to the downtown campus, according to statement from the university.
The emergency notifications go out to about 52,000 recipients.
