After multiple sales app-related robberies in Gwinnett County, the Norcross Police Department is officially making its lobby a "safe place" for transactions, it said on Facebook.

The department has placed a sign from OfferUp, one of multiple popular sales apps that allow people to sell items to each other based on location, in its lobby.

“The idea is to give you a neutral location to conduct business that is also under 24-hour video surveillance,” the department said on Facebook. “Avoid possibly becoming a victim of a crime by meeting here at the police department, 65 Lawrenceville St.”

Multiple police departments, including the Gwinnett County Police Department, have advised residents that police facilities and parking lots can be used for these transactions, which often include a buyer and a seller who have only met online. In several cases, police said, people expecting to buy expensive electronics, like iPhones, have shown up with cash to pay for them only to be robbed by the purported seller.
