DELTONA, Fla. -- The teacher accused of strapping an autistic child to a wheel chair and locking him in a bathroom pleaded not guilty Wednesday.

Biying Hu was a special needs teacher at Deltona Middle School. She was arrested earlier this month when she was accused of abusing an autistic student she says was acting up in class.

Hu's lawyer entered the written plea in DeLand on Wednesday.

Hu is suspended until the school district can finish their investigation.
