Early Friday morning in Atascocita, a deputy constable was hospitalized after inhaling an unknown white powder during a traffic stop. The incident happened around 4 a.m. on Ramsay Cascades Drive near Pierson Hollow Drive. The driver tried to evade deputies but was caught, and the powder became airborne while the vehicle was being searched, as reported by Click2Houston

A deputy was treated with multiple doses of Narcan after becoming suddenly ill from suspected opioid exposure, and paramedics transported him to a nearby hospital; his current condition remains unclear. The suspect was arrested for driving while intoxicated and evading in a vehicle, with additional charges possible depending on lab results of the airborne substance.

According to the Harris County Constable Precinct 4 on their Facebook page, Constable Herman praised his deputies for their quick actions, saying their response prevented "a much worse outcome." The incident shows the dangers officers face during routine duties, and the investigation into the substance and circumstances is ongoing.
