Arlington County police are investigating an unusual break-in and theft that took place Sunday.

One or more suspects broke into a locked house on the 5500 block of 7th Street S., in the Forest Glen neighborhood, at some point on Sunday. According to police, the suspects played beer pong while inside the house. They then allegedly stole two cars parked outside, leaving the residence “in disarray” with empty beer bottles strewn about.

The crime was reported Sunday afternoon by an adult female house sitter – a friend of the family that owns the house and the vehicles, according to police.

There is no suspect description available.
