A former Los Angeles elementary school teacher has now been charged with sexually abusing 13 children.

Paul Chapel was charged last fall with continuous sexual abuse of three girls and a boy. The Los Angeles Daily News says a revised criminal complaint filed last week adds accuses him of committing lewd acts with nine other boys and girls.

In one case, Chapel is accused of molesting a boy for three years beginning in 2006.

Chapel taught at Telfair Elementary School in Pacoima and authorities say at least one of the alleged victims was a student at the school.

He was arrested last October.

Chapel has pleaded not guilty and remains jailed on more than $3 million bail.
