The biggest badass of the month is a 54 year-old-man who was mugged in the West Village, then chased his attacker through a subway tunnel. DNAinfo explains what went down.

Jeff Hamm, 54, snatched $94 in cash and a $2 lighter from a 54-year-old man at Sixth Avenue and West Fourth Street about 7:30 a.m. Feb. 9, police said. When the victim tried to grab the items back, Hamm put up his fists and then took off running, police said.

The victim chased Hamm into the 1 train station at West Houston and Varick streets, then followed as Hamm leaped onto the subway tracks and raced through the tunnel to the next stop on the uptown 1 route, Christopher Street.

Eventually, they made it to Christopher Street and back above ground, where police caught and arrested Hamm as he was trying to enter a cab. His victim was still right behind him.
