Although the Harris County Sheriff's Office has not confirmed the number of victims, officials say that a male suspect has been detained by Cy-Fair ISD police. A second suspect remains at large, according to a statement from the school.
A Life Flight helicopter has lifted off from the campus with one victim and a second chopper just landed. Several ambulances are also on the scene amidst reports of patients suffering critical injuries.
An alert posted on the Lone Star website and sent to students via text asks that all on the Cy-Fair campus stay away from the area and seek shelter in a secure location. The website also says the campus is on lockdown and being evacuated by law enforcement.
"I had just left class out of the HSC building," student Margo Shimfarr-Evans tells KHOU.
"As we were leaving we saw the cops comings. I called to check on another classmate who was still inside the building, and she said the classroom was on lockdown and she said one of the classmates had been stabbed. It happened in the hallway. We have a lab and lecture, and down the hallway it’s all lab classes, and a classmate in the lab class got stabbed."
