Residents at the Aldon of Chevy Chase Apartments are concerned a break-in on Monday night at the complex’s management office may put their security at risk.

Montgomery County Police confirmed an office burglary at the 4740 Bradley Blvd. address of the office on Monday at approximately 11:05 p.m. Nobody has been arrested and not many other details are known at this time.

A resident of the apartments, mid-rise brick buildings just south of Bethesda’s Central Business District, said management was re-keying doors on Thursday and that residents were concerned that master keys were accessed or stolen from the office.

The tipster also said computers were stolen, which has left tenants scared that personal information has been compromised.

Representatives from Aldon Management, which manages the property and two others in Woodmont Triangle, did not respond to requests for comment.
