Multiple reports describe an incident in which a man is accused of sexually assaulting a woman after allegedly being seen prowling on an empty train late at night. The accounts state that the suspect was captured in footage moving through a train when it was not in regular use, and that he later targeted a lone woman. One report also refers to a pattern described as involving sexual assaults of two women within a two-week period, suggesting investigators believe the cases may be connected. The coverage focuses on the alleged sequence of events shown in the video, including the suspect’s presence on the train before the assault. Authorities are presented as treating the behavior as opportunistic, implying the suspect is believed to seek victims when there are few or no people around. The reports do not agree on additional specifics such as location, the exact time of night, or whether charges have been formally filed at the time of publication. Overall, the sources align on the allegation of an assault following the man’s movement through an empty train late at night.
