A woman’s quick thinking after being flashed during a morning jog was caught on video in Massachusetts.

Massachusetts State Police said the woman was running around 7:30 a.m. last Thursday on Memorial Drive in Cambridge, outside of Boston, when a man exposed himself while jogging towards her.

Video released by authorities shows the woman abruptly turn around after the man passes her and chase him down the street. She quickly caught up with him and grabbed his arm, trying to detain him, shouting for people to call police.
