Is this similar to the sick knockout “game” that some blacks are perpetrating in the US? A group of blacks seek out a lone white person to punch out (or an Asian will do), and score points if they knock the person out with one punch. They target weaker victims - women, the elderly - in their vile attacks.
Yes, quite similar. In the UK, the practice is known as “happy slapping”, because it started out just with kids running up and slapping random people while their friends recorded it on their phones. Now, it has progressed to randomly punching people in the head. I don’t think there is as much of a racial element to it as there is in the US though.
