Steven Maida was leaving the cafe on his college campus Tuesday when he saw people running. Then, he heard a girl scream: "My friend's been stabbed."
Maida said he saw blood on a stairway and several injured victims at the Lone Star College's CyFair campus northwest of Houston, Texas. One wounded woman had a hole her throat, one had a hole in her cheek and another victim had a stab wound in the back of his head, Maida said.
"I just took off downstairs running" and searching for the attacker, he said.
Maida told CNN he was among a group of students that chased the suspect, tackled him and pinned him down until authorities arrived. Investigators could not be immediately reached to confirm his account.
