The unknown suspects have attempted to gain access to homes and businesses, according to Fairfax City Police.
A similar scam has been used successfully in other parts of the region to distract a homeowner while a second individual robs the home.
The city's public safety departments offered tips for residents:
- Ask the worker for identification.
- Feel free to call the worker's company to confirm s/he is indeed an employee.
- When contacting the office, use a reliable phone number available to the public to reach the proper authority.
- Report any suspicious activity to the police department.
