A Little Rock school security guard is under investigation after a middle school student claimed the guard placed his hand inside the child’s pants.

Thirty-nine-year-old Robert Myles faces two counts of sexual assault charges stemming from the incident.  Myles has posted a $20,000 bond after his booking into the Pulaski County Jail.

Little Rock School District personnel said Myles has worked for the district since 2012 as a substitute school security guard.
