A Harker Heights science teacher and coach who was arrested Thursday as part of an online child sex solicitation sting was hospitalized Friday after complaining of a heart problem.

KWTX reports that David Anthony Balsinger was under armed guard at a local hospital, but police did not specify which facility was caring for him.

46-year-old Balsinger, a teacher at Union Grove Middle School in Harker Heights who's married and has two teenage children, was arrested Thursday after allegedly trying to solicit nude photos from someone who identified as a 15-year-old girl.

Hamilton County Sheriff Justin Caraway says Balsinger contacted the person via anonymous chat app Kik. The "girl" was actually an undercover Hamilton County Sheriff Department officer.

Police say Balsinger admitted to the behavior prior to his arrest. He has been placed on administrate leave by Killeen ISD.
