A post widely-shared Wednesday on social media across Lubbock pertaining to a mysterious black van and men knocking on doors raised concerns across the city.

EverythingLubbock.com contacted the Lubbock Police Department.  Lt. Ray Mendoza, LPD spokesman, said authorities believe the men are simple door-to-door salesmen.

Mendoza said the men appeared to be selling vacuums and carpet cleaning products around Lubbock. 

Lubbock Police said they appreciate the community bringing the incident to their attention and sharing it across Lubbock.
