A man was struck and killed by an NYC subway train in Brooklyn early Saturday, police said.

The victim, an unidentified man in his 20s, was “observed” on the tracks when he was hit by a southbound A train at the Broadway Junction subway station — located at the border of Bedford-Stuyvesant and East New York, police said.

The man was pronounced dead at the scene shortly after midnight, cops said.

“It doesn’t look like there’s criminality involved,” an NYPD spokeswoman said.
