“Transit assaults are at an epidemic level and Metro must address this urgent issue of safety so that workers and the riding public are protected,” says the union that represents bus operators.

Officials arrested Coleman James Miller for the incident that took place on the U4 bus on Tuesday morning.

Metro is accusing the union of engaging in “an unauthorized and potentially unlawful labor action that is significantly impacting riders on the X2 line.”

She was arrested by Metro Transit Police on Wednesday on charges of simple assault.

It happened on the X2.

The accident happened at H and 7th Streets NE at 12:16 p.m.

A Metrobus passenger was stabbed twice in the chest last night in Northeast D.C. and was hospitalized with non-life-threatening injuries, Metro officials said.
