PHILADELPHIA (CBS) — Police say a 35-year-old man has died after being stabbed in Center City. The incident happened shortly before 6:15 p.m. Saturday outside of the Luke’s Lobster restaurant on the 100 block of North 17th Street in Rittenhouse Square.

The victim was stabbed once in the neck, according to police.

He was rushed to Thomas Jefferson University Hospital, where he later died.

Police say an arrest has been made.

Sources say the stabbing stemmed from a fight on a sidewalk possibly between two homeless men.

Detectives searched down the alleyway for the knife, which police say the suspect put into a nearby dumpster. It’s unclear if the weapon was recovered.

Onlookers can’t help but feel for the victim.

“Especially if he has kids and stuff,” onlooker Francis Spence said. “It’s a sad thing — like on a warm evening like this, your family got killed.”

An investigation is ongoing.
