SAN ANTONIO -- Cuts and bruises mark 15-year old Brandon Yee's neck. He says he was choked at Kirby Middle School as punishment for being tardy.
"I had sprained my leg so I was walking slow," says Yee. "The teacher was complaining because I was walking slow so I was like, 'I sprained it'. So he thought I was playing with him."
The school district confirms there was an altercation Monday morning, but wouldn't go into details.
But News 4 WOAI caught up with students who witnessed the alleged assault.
"[The teacher] grabbed him, he threw him against the wall and dragged him 10 to 15 feet and [Brandon's] shoe came off," describes Esmeralda Lopez, who was sitting in the class at the time.
Esmeralda says another teacher approached her in the hallway and told her not to tell anyone about the incident.
"They try to hide everything," says Esmeralda's mother, Christina. "It got me upset they told them not to say anything about it."
The teacher's aide is no longer with the school. Though students allege other teachers were inside the room, the district would not confirm that or comment on whether other employees have been disciplined.
