From the February 2012 edition of the Glover Park Gazette:
In the early morning hours of December 24, two patrons at the Mason Inn (2408 Wisconsin Ave.) got into a fight, and one came away with a gash to the forehead that required eight stitches to close, according to a police report. In a dispute over whether one of the men was “harassing” a third person, the man accused of harassment headbutted his accuser, whose forehead was lacerated. The two men “were immediately separated and escorted out,” reports bar co-owner Fritz Brogan. The injured man drove himself to Sibley Hospital, where his wound was treated. The event is under investigation by ABRA.
