CTA

A man who has been arrested 32 times by Chicago police since 2014 robbed and then engaged in a “firefight” with a concealed carry holder on a Green Line train during the Friday afternoon rush hour, authorities said Sunday.

Chicago police say they know who fatally shot a man outside a South Side liquor store and shot a woman who was sitting on a nearby CTA bus in December. But prosecutors refused to charge the man with shooting either person due to “self-defense,” according to court records and the man’s defense attorney.

A Chicago man who prosecutors said forced a CTA bus operator at gunpoint to drive him to an off-route location has received a one-year prison sentence in a plea deal with prosecutors.
