SCHERTZ, Texas – A San Antonio police detective has been suspended 30 days after an internal affairs investigation determined he called law enforcement under false pretenses and sent vulgar and degrading messages to his former girlfriend, city discipline records show.

Detective Arthur Lopez, a 17-year veteran of the force, was handed the suspension in late June. He is scheduled to return to work after the suspension ends late next week, records show.

The messages were reported to SAPD in early January, weeks after Lopez requested Schertz Police Department officers take part in a civil standby at the residence of Lopez’s former girlfriend, records show.

Lopez told officers on Dec. 13, 2023, that he wanted them there while he informed his ex that he wanted her to stop calling him, according to records.

He told officers the woman had contacted him earlier in the day while she was having sex with an unidentified individual in “an attempt to harass, embarrass, annoy and shame him,” the records state.

At the scene, however, officers determined it was Lopez who had attempted to call the woman and her husband multiple times that day.

The woman told Schertz police she feared for her safety and showed officers text and Facebook Messenger messages sent by Lopez earlier in the day, records show.

In one message, Lopez called the woman a “stupid f----n whore.”

The woman also shared messages from Lopez in which he referred to her as a “dumb f----n c---,” and wrote “Just do yourself a favor and kill yourself,” discipline records state.

Lopez called the woman’s husband six times in 10 minutes before leaving a voicemail and had attempted to call her as well on Dec. 13, records show.

Lopez failed to provide Schertz police his phone records for that day or an alleged recording of the woman’s call to him, according to records.

“Based on the body-worn camera video footage, Detective Lopez’s motivations for requesting police assistance was not for the stated purpose, but rather may have been to learn of (redacted)’s whereabouts, discover whether (redacted’s husband) knew of the affair, and/or to elicit communication from either (redacted) or (redacted’s husband),” discipline records state.

Lopez was issued a criminal trespass warning by Schertz police and ordered to stay away from the woman’s home.

SAPD’s internal affairs investigation determined that Lopez brought discredit on himself and the department.
