A person was killed and seven others injured after a man attacked people with a knife at a shopping mall in southeastern Poland on Friday.
Police has detained a 27-year-old man after the attack in Stalowa Wola, local media reports said.
"The man, dressed in a gray sweatshirt and gray sweater, entered the main entrance with two knives and blindly attacked the people in silence," RMF 24 quoted a witness as saying.
Police has denied the attack to be a terrorist attack.
