Jaime Castro, a longtime officer who leads the Dallas Police Association, the city’s largest and oldest police union, was placed on administrative leave Friday while the department conducts an internal affairs investigation.
The exact nature of the investigation was unclear Monday. Responding to a list of questions from The Dallas Morning News, a police spokesperson said no further information would be provided to “protect the integrity of the process.”
“The Dallas Police Department expects every member of the organization to uphold the highest standards of integrity, professionalism and accountability,” Dallas police Chief Daniel Comeaux said in a statement through the spokesperson. “Any allegation of misconduct is taken seriously and investigated thoroughly and fairly.”
Castro did not immediately return messages seeking comment Monday morning.

Castro, 52, joined the department in 1998. He holds the rank of senior corporal and is assigned to the department’s alarm unit, which is housed in the office of the police chief.
Association members elected Castro president in January 2024, succeeding Mike Mata, who held the job for six years. Before then, Castro had served on the union’s executive board since 2016.
As president, Castro has been a prominent voice for rank-and-file officers. He is a common fixture in debates around City Hall’s public safety obligations, particularly in the lead-up to a vote on Dallas Hero’s S, T and U propositions last fall. Propositions S and U ultimately passed.
Proposition S waives the city’s governmental immunity and allows residents to sue if they believe Dallas isn’t following its charter, ordinances or state law. Proposition U directs the city to work toward a 4,000-officer force, devote half of new annual revenue to pensions and public safety and ensure the department’s starting pay is competitive in North Texas.
