A woman who walked into the Lincoln Tavern on West Broadway on the night of Oct. 15 and spotted her ex-boyfriend kissing another woman grew enraged and went up and punched the other woman, a BPD detective said today.

And then, after she was kicked out, she waited for the woman outside and, despite the presence of a bar bouncer who'd agreed to walk the woman home, attacked her again, stealing her keys - of which she's since taken video to taunt the victim online.

BPD Sgt. Det. Kenneth O'Brien told the Boston Licensing Board the women did not know each other before the incident. The attacker faces possible criminal charges in South Boston District Court.
