The attack happened back on Thursday at 12:15 a.m. onboard the SEPTA northbound Broad Street line.
The victim, 20-year-old Dewayne Taylor is seen dozing in his seat, listening to his ipod.
In the doorway, the assailant is standing with a young boy, about three to five years old.
He tells the child to sit down.
Then, he pulls out a large hammer out of a black and yellow book bag, and proceeds to pummel the victim.
After striking Taylor a number of times, the attacker grabs Taylor by the shoes and pulls him down to the floor, where the attack continues.
Then, the man throws Taylor off the train, where they struggle some more before the attacker disappears out of sight.
"According to the victim, the male continued to assault him and tried to throw him into the track area," said Det. Kenneth Roach of the Philadelphia Police Dept.
Taylor told Action News last week that all throughout the attack, the man kept chanting something, and he distinctly recalled the word "Allah."
Police were stunned that some 20 passengers onboard the train scattered, and did nothing to stop the attack.
"I think somebody should have helped that guy," said Det. Roach. "I understand the guy had a hammer, but they outnumbered him by at least 10 to one."
Monday night, Taylor's mother says she's not sure she wants to watch the horrific video of the attack on her son.
"You know, I just hope they catch him because my son didn't deserve it, and I'm not just speaking out for my son," said Tracie Taylor. "I'm speaking for all the victims and for the public, we need protection out there, and my son is fearful to return to work because he has to ride SEPTA."
