A warning from Harris County Constable Precinct 1:

As a precautionary measure only, Precinct 1 suggests you be wary of any flyers placed on your vehicle. A Harris County Sheriff's Deputy suffered an adverse reaction after coming into contact with a flyer left on his vehicle, located at an HCSO facility at 601 Lockwood. We are attaching a picture of the flyer to make you aware of what it may look like. The flyers appear to have been laced with Fentanyl.
