Not all the houses and apartments in one of the District’s most desirable residential areas have central air-conditioning. Some have window units, and, according to police, that has apparently offered an opening to burglars.

In recent weeks, police said, residents between Dupont and Logan circles have been victimized by six similar burglaries. Five have occurred in the past 12 days. Most were within two or three blocks of the others, and none was much more than a half-mile from the rest.

In one of the latest burglaries, carried out during the day Thursday in the 1600 block of 17th Street NW, police said, entry was gained “by pushing out the window air- conditioning unit.”

That burglary followed one on Feb. 21 around the corner, in the 1700 block of R Street NW. There, too, police said, premises were entered during the day by pushing out the window unit.

In both cases, police said, electronic items were taken.

Four others in the same area since January seem to be “fitting the same pattern,” police said last week.

The first of those four came Jan. 17, in the 1800 block of S Street NW, police said. The others came Feb. 23, in the 1500 block of 17th Street NW; Feb. 25, in the 1900 block of Florida Avenue NW; and Friday in the 1700 block of P Street NW.

In the Friday burglary, police said they were looking for a male about 5-foot-9 who wore a spotted black-and-white jacket.
