Tulsa police said a second person has been arrested after a video started circulating online of a couple having sex in front of a child.
TPD said the video was sent to their Facebook page in August, which is when officers started their investigation.
The video shows a man and woman engaging in a sex act while a 3-year-old boy watched.
The man in the video was later identified as 27-year-old Antonio Washington. Officers arrested Washington on Thursday.
Kentavya Mack, 25, was identified as the woman in the video and she was arrested a few days later.
Both Mack and Washington were booked on lewd molestation complaints.
