NEW YORK (CBSNewYork) -- An incident in which a student is seen on video being beaten by a New York City teacher has left the boy's mother up in arms.
Kristof John, 15, was running late and racing into his building at Westinghouse Career and Technical Education High School in Brooklyn when he swiped his security card and it didn't work. When he moved to go through anyway, suddenly a teacher, identified as Stephan Hudson, stepped in.
On the surveillance tape, Hudson appears to grab the boy by the arm, yank him around, and pull him towards a table. After much tussling, Kristof, who is barely over 5-feet-tall, went down to the ground.
Diane John, the boy's mother, said she never got the real story and was told that her son had started the whole thing.
"They told me a different story," she told CBS 2's Dick Brennan.
The boy's mother said she asked her son "How come what you're saying to me and what they're saying to me is not adding up?" To which her son replied, "Mom there is a video, if you see the video, you're going to believe me."
Diane John said she didn't see the surveillance footage until Tuesday.
In a statement, the Department of Education said "The teacher was found to have engaged in corporal punishment and was disciplined." However, they would not say how Hudson was disciplined.
The DOE said the teacher is still at the school earning $95,000 per year.
"He's a cool guy, that's all I know," said one student, when asked about the teacher.
"He was my tech teacher so I never really...he was never really a bad guy. He was so nice," another student said.
The mother said the boy suffered from a sore back. She transferred him out of the school and the boy now lives with his aunt in Grenada.
Schools Chancellor Dennis Walcott has promised a thorough investigation.
"If there was a cover-up, we'll get to the bottom of it. I don't like people to cover-up, I don't like people to hide the facts...I don't like people...touching our students in any way that's appropriate," Walcott said.
Diane John's family is from Grenada and the Grenada Counsel General in New York said he'll investigate.
