A man has been stabbed to death in a Poundland store in Oxfordshire.
Officers were called to the shop in Bury Street, Abingdon, at about 11:20 GMT, Thames Valley Police said. A 36-year-old man from the Abingdon area has been arrested.
Paramedics said the victim died from his injuries at the scene and a second man nearby suffered a minor injury to his thumb.
Police said officers were investigating whether the two were connected.
Kash works at a nearby Spar shop and said after the stabbing a man, who was known to locals in the area, tried to push his way into the store.
He said: "He approached with two knives in his hands and he tried to enter. He said 'I just want to shake your hand' and we held the door closed.
"Then a policewoman caught up with him and Tasered him."
Supt Rory Freeman said: "Members of the public will understandably be shocked and upset by this incident today, which has happened in a very public place.
"At this stage, this is not being treated as a terrorist incident."
On Twitter, Alf Merkin wrote: "The fact my family was here while this was happening is just scary."
Poundland chief executive Jim McCarthy said he was "shocked" that one of the company's customers had been killed.
He said: "Our sympathy and thoughts centre on the family of the deceased and of course with other customers and colleagues who were in the store at the time of this terrible incident."
Poundland is closed, the area has been cordoned off and officers remain at the scene.
