The off-duty Waco Police Officer who was placed on administrative leave after he was arrested in January on a prostitution charge has now been re-arrested by investigators from the McLennan County Sheriff's Office.

Evidence recovered by the sheriff's office led deputies to obtain an additional arrest warrant for invasive visual recording, which is a state jail felony. The charge will be in addition to the misdemeanor prostitution charge Lopez was already facing.

The McLennan County Sheriff's Office first arrested Willy Lopez, 35, on Jan. 15 after investigators said he tried to meet what he thought was a woman for sex -- only to find out it was actually an undercover detective.

According to a search warrant previously obtained by Channel 6, Lopez first texted the undercover detective on Jan. 12 in response to a sex advertisement the detective placed on Backpage. On Jan. 15, Lopez drove to the Deluxe Inn off I-35 in Waco, where he thought he would pay $60 for 15 minutes of sex, that warrant said.

Two detectives were waiting at the Inn, but Lopez spotted them, authorities said.

"Tell ur buddies not to stick out like pigs next time," Lopez allegedly texted, according to the warrant. "How do u like being a cop? How many years u have in the force?"

But, despite that exchange and his suspicions, Lopez still agreed to try to meet again, authorities said. The undercover detectives convinced him to meet in the Fuego parking lot later that day, and detained Lopez when he arrived, according to the affidavit.

Investigators searched Lopez's phone the next day and found video of Lopez having sex with a real, known prostitute, according to the warrant.

"We are aware of the incident. It is not our case so we cannot comment on its specifics," Waco Police Spokesperson Sgt. Patrick Swanton said at the time. "By policy, the City of Waco does not comment on personnel matters. The criminal justice system is in action and will take it’s course."

On Thursday, after the second arrest, Sgt. Swanton said Lopez would remain on administrative leave pending the outcome of the Waco Police Department's internal investigation.

As of 4 p.m. Thursday, online McLennan County Jail records still listed Lopez as being in custody on $2,500 bond.
