About 30 youths attacked and robbed a man in the subway concourse at 15th and Market Streets yesterday afternoon and then were chased out by police officers, who made six arrests, authorities said.
Nathan Butcher, 19, of the city's West Oak Lane section, was walking through the concourse about 12:30 p.m. when he saw the youths, ranging in age
from about 13 to about 18, running toward him and shouting, according to police Detective Joseph Sweeney.
One youth ripped two gold chains from Butcher's neck. While Butcher struggled with the youth, several others started to punch him, Sweeney said. Butcher, a maintenance worker at the University of Pennsylvania, broke free and fled. He ran onto the subway platform on the east side of the tracks, jumped down and ran across the tracks, scrambled onto the west platform, and raced up to street level, where he found police Officer Mary Gannon, Sweeney said.
