A man was arrested after investigators said he put a great-grandmother in a choke hold inside an Houston ISD elementary school.
Gustavo Mendizabal, 61, was in court Thursday to have an attorney assigned.
Deputies said Mendizabal attacked a woman who was picking up her great-granddaughter at Looscan Elementary School on April 15.
Investigators believed Mendizabal and the victim have a previous history together.
Mendizabal is charged with injury to the elderly and is being held on no bond.
