The officers spoke to the 17-year-old girl “who they believed was a victim of human trafficking” and determined that Antonio Lettmen of Los Angeles had taken her child and demanded a ransom.

LBPD Night Vice Investigation Unit personnel investigated the matter and were able to recover the child, according to police. No further details were released.

During the course of the investigation, police determined Lettmen had trafficked the 17-year-old woman and assaulted her.
