Transit Police report arresting a Dorchester woman after allegedly she tried to end an argument about how long two people were taking in the restroom at the Ashmont Red Line station by decking them.
Police say that shortly before 9:30 p.m. on Thursday, the two were taking longer in the restroom than Tasheaka Buchanan, 27, preferred, so she began banging on the door demanding they get out, already.
A few moments later the couple emerged from the bathroom and an argument ensued about Buchanan's agressive behavior and lack of patience. Buchanan responded by striking both victims with a closed fist in their heads.
A T ambassador managed to separate the parties before Transit Police officers arrived and arrested her on assault-and-battery charges. Police say she already had warrants out for her arrest on assault and battery, four counts of assault and battery with a dangerous weapon, receiving stolen property, larceny, malicious destruction of property and violating an abuse prevention order from four different courts in Boston.
