A Midland Lee High School student is recovering after he was severely beaten up by another student.

Run Ceu, 17, was left bloodied and bruised in a bathroom on the campus while school was still in session Thursday.

"When I look at him it's too bad … how can they do [something] like that to somebody?" questioned Ceu’s older brother Siang Uk.

Uk says Ceu had been lying on the floor anywhere from five to 10 minutes before a teacher found him.

"He told me that a teacher performed CPR, but if he [didn’t] perform CPR he would be dead, because he [couldn’t] breathe," said Uk.

According to an MISD press release, the student received immediate attention from campus nursing staff until he was transported by EMS to the hospital.

MISD police officers quickly began to review video surveillance and found and arrested their suspect for aggravated assault.

His identity hasn't been revealed, but Uk says it’s his brother's best friend.

An early investigation revealed there was an altercation between the two students that escalated.

"They eat together, they go together church, so they are best friends,” Uk explained. “Sang Cung is younger than him, he can't beat him like this, no way.”

Uk says his brother specifically told him and police who is responsible.

"He told him that three African Americans beat him,” said Uk. “They need to find the real suspect who did this."

But the school district says their police officers are confident in the results from the investigation and surveillance video.

Ceu’s family says they are determined to get to the bottom of what really happened.

The good news is Ceu is at home and expected to fully recover.

“Our campus administrators and district police officers responded immediately and within a few hours were able to make an arrest. The safety our students remains our number one priority. While campus administrators and law enforcement investigated, other MISD staff members provided support for the injured student and his family,” commented Woodrow Bailey, Director of Communications.
