DALLAS (TIP): A Dallas police officer accused of sexually abusing a woman while on duty and in uniform, has been arrested. Officer La’Cori Johnson, 28, allegedly forced a woman to perform oral sex on him before having sex with her in the back of his patrol car on Sept. 9, 2013.

“You don’t have to go to jail if you do what I tell you to do,” he said, according to an arrest affidavit. The unidentified woman said she obeyed the officer’s demands because he was armed and she feared going to jail, reported NBCDFW. The Dallas-Fort Worth station said the whole incident started when Johnson pulled over the woman and another person, performed background checks on both and then told the friend to leave.

The officer, who had been with the department since 2009, told the woman there was a warrant out for her arrest and told her to get into the back of his car, she said. Johnson drove the woman to a dead end behind the Pecan Square Apartments and parked. Then he got into the backseat and removed his gun belt, according to NBCDFW.

At this point, he allegedly made his sexual demands. “With any sexual assault, the victim is going to have lasting damage from that attack; but in this particular case, the damage extends beyond the victim, and it impacts the entire public,” attorney Kimberly Priest Johnson told ABC affiliate WFAA. The woman reported the incident to police on Oct. 4, 2013. Johnson was immediately placed on administrative leave.

At the same time, a criminal investigation by the department’s Public Integrity Unit was initiated. That investigation was followed by an Internal Affairs investigation that began on Jan. 24 of this year. On January 28, Johnson was questioned by Internal Affairs detectives. He later resigned from the department and was immediately arrested and booked into the Dallas County Jail. He was later released the following day after his bond was paid. The sexual assault charge is a 2nd degree felony.
