-- Surveillance video from Greece appears to show the beginning of a bar fight on Friday that killed a 22-year-old American.
In the video, which was shared with ABC News, two groups appear to clash on the street outside a bar on the Greek island of Zakynthos. A large crowd remains outside the bar for several minutes.
Bakari Henderson, a recent graduate of the University of Arizona, was battered to death in the street after the fight broke out, around 3 a.m. local time. In the video, he appears to be fleeing people when someone body-slams him into a car and a group of men begins to beat him.
Henderson's friends who were in Greece with him told ABC News that the suspects were "looking for a fight" and punched him first. He attempted to get away from the mob during the brawl, his friends said.
By the time Henderson's friends reached him, the attackers had dispersed, the friends said.
Henderson suffered head injuries, the coroner said. All the strikes were to the head, and he did not appear to have defensive wounds on his body, she added.
While the coroner couldn't determine exactly when Henderson died, she told ABC News that he was pronounced dead at the hospital.
One of Henderson's friends, Travis Jenkins, described Henderson as a "peacemaker," saying that it was not in his nature to "act aggressively."
At least eight people have been arrested in connection with the killing, local police said. Among those arrested were a British citizen of Serbian origin who is temporarily employed in Greece as a bouncer and a Greek national who works at the bar on the island, police said. Six Serbian tourists were also arrested after they were identified on surveillance footage.
Zakynthos Mayor Pavlos Kolokotsas told ABC News that both groups involved had been drinking extensively.
Those arrested appeared in court Saturday and pleaded not guilty, police said.
