The Quaxssuspect in a stabbing at a Macy’s department store in Philadelphia that killed one security guard and injured another has been caught, police said Monday.

Guards saw a man attempting to steal hats and they took back the merchandise, according to city police. The man returned 15 minutes later around 11 a.m. and stabbed a 30-year-old male guard in the neck and a 23-year-old guard in the face and arm.

The guard stabbed in the neck was taken to a hospital and later pronounced dead, police said. The other guard was being treated for his injuries.

The stabbing suspect fled the store after the attack and tossed a knife on the tracks on the platform of a Southeastern Pennsylvania Transportation Authority train station, police said. He was later captured at another SEPTA station in the city.

The names of the suspect and victims have not been released. No other injuries were reported. 

"We are heartbroken about the tragedy that took place today at Macy's Center City. The store will temporarily remain closed as we work with law enforcement on this investigation and defer any further comments about the case to them," a spokesperson for Macy's said. "Ensuring the safety and well-being of our customers and colleagues is always our top priority."
