His action on May 1 was recorded by one of passengers before it was posted online, reported TMZ.
The subway was heading towards Brooklyn when Coleman had a meltdown and screamed at passengers.
Coleman couldn't hide his anger after a guy and a girl in the subway tried to figure out where they knew him from.
It has been confirmed that Coleman was completely sober when having a meltdown in the subway.
The actor said that his rants about humanity were responses to what's happening in Baltimore right now.
