Montgomery County police are investigating five house burglaries that occurred in one night this week in a North Bethesda residential area, Officer Rick Goodale, a department spokesman, said.

Property was stolen from homes in the Tilden Lane and Roseland Drive area along Old Georgetown Road between Wednesday night and Thursday morning.

Goodale said at least two alleged burglars were seen on surveillance video, but police don’t have a description of them because their faces were concealed.

All five homes that were entered had been left unlocked, according to Goodale. Nearby homes with locked doors were not burglarized.
