SAN ANTONIO -- Alamo Heights Police arrested David Lee Gabler, UTSA's Associate Vice President for University Communications on Friday afternoon on charges of aggravated sexual assault of a minor.

Police said they noticed activity in the cabin of a parked vehicle in the 500 block of Argo. Upon closer examination, officers observed a 47-year-old male and a 15-year-old male in the car along with evidence of sexual activity.

Police said the 15-year-old revealed that he met Gabler in an online chat room, verifying the information based upon evidence from their cell phones. Gabler picked up the boy from his home before engaging in the sexual activity, and police said Gabler knew the boy's age beforehand.
