A 54-year-old woman died on Saturday after another woman went on a stabbing spree at a museum in northern Italy, local media reported.
Another three people were injured in the attack at the museum in the town of Canneto sull'Oglio, the newspaper Repubblica reported. 
The attacker, a 58-year-old Polish woman, was arrested shortly afterwards. Her motive was not clear but police were not ruling out the possibility she suffered from a mental illness.
