HOUSTON (KTRK) -- A Houston Police Department officer has resigned from his job following an internal affairs investigation into possible pornography charges. Eyewitness News is not identifying the officer because no criminal charges have been filed.



A search warrant obtained by Eyewitness News shows that in January of this year, the officer, who's just 22 years old with less than a year on the force, was found at a Clear Lake-area home with his 17-year-old girlfriend. The warrant shows he was given a ticket for a curfew violation. That initiated an investigation that lasted until this month.



The warrant shows the Houston Police Department was trying to determine whether a crime had occurred. In Texas, the age of consent is 17, but our legal analyst Joel Androphy says the relationship was still dicey.



"It was inappropriate, but she was the age to consent," said Androphy.



The search warrant shows the officer's phone was seized. Investigators found multiple images and videos of the young officer and his teenage girlfriend in multiple sex acts. The young woman told investigators she was the one who initiated the videos. The couple also communicated via Facebook. Under Texas Law, even though the age of consent is 17, any images of people under 18 could be considered child pornography.



"If you have a sexual act with a girlfriend who is under age, obviously that's a crime, but if she's 17 or over, it's not a crime," explains Androphy, who says the law can be confusing. "But, it may be child porn (if she's under 18 or) if you're using it in some way to promote it."



HPD says the officer was relieved of duty on February 3. Then on April 3, he resigned from his job. The Houston Police Department says it doesn't believe any child pornography charges will be filed. Androphy says this is one incident where the officer is held to a higher standard.



"Because he's a cop, he's under a microscope, and he's expect to obey all laws, no matter how isolated and how unusual," he said.
