Passengers on a Philadelphia SEPTA subway car looked on in terror as a male passenger repeatedly stabbed another man with a pair of scissors.

According to the Philadelphia Daily News, a subway car on the Broad Street line was headed to a stop on Oregon Avenue on June 10 when two men got into a dispute. The argument quickly turned violent and led to one man being stabbed in the torso, arm, face and shoulder.

The 46-year-old victim was rushed to Hahnemann University Hospital following the incident and needed 35 stitches for an abdominal wound and 15 stitches to close a gash on his forehead.

The man’s alleged attacker, Sheldon Mullings, was found at Methodist Hospital, where he obtained treatment for a cut above his eye.

Mullings, 35, is expected to be charged with aggravated assault and related offenses.

Apparently, no passengers attempted to intervene as the attack took place.

“Lots of people were on there and saw this happen,” Sgt. Cynthia Kelly told the Daily News. “No one called 911. Everyone just got out of there.”

SEPTA supervisors searched the car for evidence of the attack including a weapon, or blood, but couldn’t find anything. Spokespersons for the transit authority said video surveillance on the Oregon Avenue platform did not show anyone who appeared hurt getting off the car, leading them to believe that the incident did not occur on one of their trains.

But authorities insisted the attack occurred on the subway.

In 2008, SEPTA commuters who experienced violent crimes expressed their concerns to Philadelphia City Council, according to 6ABCnews.com As a result, SEPTA officials said they would upgrade their video surveillance, increase its own police presence and improve interaction with city police.

According to authorities, the peak of SEPTA’s violence occurs in the afternoon hours, though most of the crimes during that time are committed by teenagers.
