NEWARK, New Jersey (AP) -- A substitute teacher is accused of using a string to choke a 7-year-old student who had not done his homework.

Albert Coleman, 59, is accused of slipping a string around the child's neck and drawing it tight, police said.

He was fired by the Newark school district, and police charged him with aggravated assault following Monday's incident at the Elliott Street School.

A Newark Public Schools spokeswoman said the incident happened to the second-grader at an after-school program and said the teacher was terminated immediately
