Knife attacker in Duisburg stopped by his own father. First he stabbed a nine-year-old girl and then the ten-year old boy.

A passer-by shouted at the knife attacker and threw a flashlight at him to get him away from the children. The attacker then attacked this witness. Then the father of the alleged perpetrator arrived and was able to stop the dramatic event. The two victims were out of danger, a police spokesman said on Thursday night. The crime occurred on Wednesday around 12 p.m. in the middle of a street.
