The East Chicago Police Department is offering the use of its headquarters parking lot and lobby — with a police officer present, if you like — for residents looking for safe spaces to conduct transactions arranged online.

Dubbed “Operation Safe Sale,” authorities in the northwest Indiana town said the program is a response to safety threats for those engaging in cash transactions involving items advertised on the Web or other classified ads, the Chicago Tribune reports.

Tales of Craigslist-related assaults and robberies, where victims are lured to locations with the promise of a sale, aren’t uncommon.
