ATHENS — Nine men were arrested and charged this week with intentional homicide in a brutal attack outside a bar on the Greek island of Zakynthos that left an American tourist dead.

Five of those men were ordered to be jailed ahead of their trials, a police official with knowledge of the case said, after an initial hearing on Wednesday. The other four suspects will have hearings later this week.

The American, Bakari Henderson, 22, was attacked by several men early Friday in the island’s popular party resort of Laganas, renowned for the rowdy, alcohol-fueled antics of young tourists.

The investigation and witness accounts suggest that the brawl began inside a bar after an argument about a female bartender around 3 a.m. on Friday. Things quickly escalated.
