Monday, January 26, 2026
HARRIS COUNTY, Texas (KTRK) -- A Harris County Sheriff's Office sergeant was arrested at work and is now being held in the Harris County Jail, according to online records.

Multiple law enforcement sources say the sergeant, identified as John Black, 46, is accused of sending sexually explicit photos of himself to an underage teen in Florida. Online records show Black was arrested Monday afternoon at offices that house the sheriff's office Internal Affairs Division.

Black is a veteran officer who previously worked in the department's homicide unit and has appeared publicly in the past discussing murder investigations. He was arrested on a fugitive warrant out of Leon County, Florida, which is the Tallahassee area, for allegedly sending graphic photos to a minor.

According to state law enforcement records, Black has been with the Harris County Sheriff's Office for 23 years, including 21 years as a peace officer. His most recent assignment was with a violent persons warrant task force, known as VIPER. He has also worked in the jail and homicide, sources say.

The sheriff's office has not yet responded to a request for comment, so Black's employment status remains unclear.



He is being held without bond until he appears before a magistrate, which is scheduled to happen late Monday night.
