America apparently has exported the "Knockout Game."
In Italy, a restaurant waiter died after being punched in the head while walking in the city center in Pisa, not far from the famed Leaning Tower, reported the Italian language Il Gazzettino and the English-language The Local.
Zakir Hoassini of Bangladesh, who worked in an Indian restaurant, had been out walking in the city center when he was hit in an attack characteristic of the so-called Knockout Game, a vicious, racially charged act in which apparently random passers-by are punched.
Hoassini died only a day after the attack.

The Local said the murder has caused uproar among Pisa's Bangladeshi community, which rallied Tuesday night in the area of the attack, demanding "truth and justice."
Hundreds of examples of the Knockout Game are documented in Colin Flaherty's book "White Girl Bleed A Lot: The Return of Racial Violence to America and How the Media Ignore It."
Pisa police said they believed they were close to finding the attacker after a surveillance camera video showed the man, described as Italian with a "hefty" physique, provoking Hoassini then punching him.
The reports said the suspect was with several others.
The Local said one theory is that the gang was playing the Knockout Game, which would be the first reported attack of its kind in Italy
But the attacks, mostly by black youth against whites, have been reported all over the U.S.
For example, the New York Daily News reported in March that an attacker was caught on video launching "a hellacious haymaker" that knocked out Kyle Rodgers, 23, after he had left the Sweet & Vicious Bar and was heading to another bar.
There were two reports of assaults near Iowa State University in Ames. Suspected are a number of black individuals who were riding around in a car, apparently attacking victims randomly.
One of the most notorious cases of racial violence in recent history took place three summers ago at the state fair. A police officer dubbed it in his report "Beat Whitey Night," based on what black people were chanting when they rampaged through the fair grounds, beating up fair goers and attacking police.
And in another one of hundreds of reported cases, John Bannon, 53, died after at attack in Baton Rouge, La.
It was 9:30 on a Friday night in early February. Bannon was a few blocks from his home when witnesses say he encountered 19-year-old Windall Lavel Herring and a 15-year-old accomplice. They punched him in the face. His head hit the ground. He lingered for a few weeks, then died.
The Advocate in Baton Rouge says the two teens attacked Bannon in an attempted robbery, or to see who could hit harder or possibly for another reason, police spokesman Cpl. L'Jean McKneely said.
It was hardly hardly the first black-on-white violent attack in Baton Rouge. Last May, a black mob attacked a white family who had stopped for gas at a convenience store near a freeway.
The police report describes how one of the attackers "approached the white male victim" and the defendant "told him he was in the wrong neighborhood and he was not going to make it out." The victim said that's when he "was punched and knocked to the ground."
His wife got out of the car and ran to help her husband.
"He continued to struggle with the defendant and was eventually knocked unconscious."
His wife told police, "after running to help her husband, she remembers falling to the ground and (being) knocked unconscious."
Then the attackers beat the couple's teenage daughter. The man suffered a broken eye socket, a broken nose and several cuts on the face.
