Arlington Police Officer Arrested on Sexual Assault, Official Oppression Charges

Police seek tips during ongoing criminal and internal probes.

Overview

  • Arlington police said they took 36-year-old Officer Derreck Dean into custody and charged him with one count of sexual assault and one count of official oppression.
  • Detectives said he first met the woman during a call for service on April 11 and then returned to her home three more times between April 17 and the early hours of April 18.
  • Police said the later visits were not tied to any call for service, and one visit included the alleged on-duty sexual contact.
  • Officials said his body-worn camera was covered during all three return visits, limiting any video record of what occurred.
  • The department placed Dean on administrative leave on April 21 and says he remains on leave as it investigates possible additional misconduct, with tips directed to Detective Donalson at 817-459-5632.
