CLEVELAND -- Some Cleveland special needs students and their parents say they are not being supervised properly.

They held a protest outside of Martin Luther King High School last week after the students say they were left alone part of the day Monday and Tuesday.

One student took cellphone video that he says shows they were alone and locked out of their classroom last week.

"We took the OGT, then went to gym and lunch and we were left on our own," says Milton Loftis, a sophomore.

Some of the students are in wheelchairs and others have seizures. The district says it is looking into the allegations and trying to verify the video.
