The Wednesday night incident is startling, particularly because it occurred one week after a SEPTA concourse confrontation at 13th and Market streets left 36-year-old Sean Conroy dead, NBC 10's Mike Strug reported.

The medical examiner said blunt trauma that induced an asthma attack resulted in Conroy's death last week.

In Wednesday's alleged attack, a woman said she got off a bus at 13th Street and walked underground to Eighth and Market streets at about 8 p.m. Police said she traveled a route used by thousands of commuters every day, along SEPTA concourses and through the Gallery at Market East.

"I'm not going to be a victim," said the 23-year-old victim, who identified herself as Tyesha. "I'm not going to be scared to walk out my front door. I'm not going to be scared to go into my city and shop. I am not going to be scared to make moves simply because children are out running wild."

The woman told police she then saw about a dozen young people, including males and females. The woman said someone said "excuse me" as she walked by, words were exchanged and suddenly she was kicked to the ground by a male, punched by a female and kicked in the face by a female before the rest of the group jumped in.

"Somebody ran up and actually kicked me in my back," Tyesha said. "After this happened, I fell to the ground. I had lost a tooth on the left side of my mouth, someone pulled me by the back of my head, I was kicked in my face by both male and female (attackers)."

The woman said her wallet was taken along with a debit card and other items worth a total of $175 before the teens ran off.

The woman then ran to Eighth and Market and asked for help from a SEPTA cashier, who called police.

SEPTA police then stopped the train at the Fairmount subway station on the Broad-Ridge spur, where the woman was able to identify five of her attackers, police said.

Police said arrested were: a 16-year-old girl; a 17-year-old boy; Stanley Poland, 19, of the 1200 block of West Firth Street; Christine Wearry, 19, of the 2500 block of North 12th Street; and Tamira Sinkler, 20, of the 2400 block of North 10th Street.

They have been charged with aggravated assault, robbery, criminal conspiracy and related counts.

The woman suffered a lost tooth, a cut on the inside of her lip as well as bruises to her forehead and left cheek. She was treated at Thomas Jefferson University Hospital.

The incident occurred in the concourse of the Gallery at Market East shopping mall, Strug reported.

Police said they are continuing to investigate.

Tyesha said she hopes the arrests send a message.

"If we make examples out of the ones we are able to apprehend, then I feel like that will send a message to the rest of them," Tyesha said. "Like, 'Look, we're not playing -- you’re not getting away with this. You took my life, you could have taken another. Enough is enough -- it stops here."
