The Harris County Sheriff’s Office District 4 substation, located at 16715 Clay Road, is now offering a safe meeting place to complete person-to-person sales transactions. Law enforcement will be on site from 6-8 p.m. on Tuesdays and Thursdays to ensure the safety of residents completing sales arranged on web-based shopping sites such as Craigslist. Deputies will not be involved in sales negotiations, but will be available solely to ensure the safety of those involved. For future updates about the safe exchange zone, follow them on Twitter @HCSOTexas, find them on Nextdoor, or like them on Facebook.
