A British tourist was stabbed to death by a taxi driver during a brawl on the Greek island of Zakynthos early Wednesday, ANA news agency reported.
Four friends of the 19-year-old victim were also injured in a brawl with two taxi drivers on a square in the town of Laganas, DPA reported.
Police said that, according to first reports, a row had erupted after the British men kept pointing lasers at parked taxi drivers waiting for custom.
The police arrested the alleged perpetrator and the second taxi driver involved in the brawl.
The four injured men were not in a critical condition, officials said.
Laganas has a reputation for heavy-drinking tourists, many of them British, who often cause trouble for the local population.
"We have to decide what kind of tourism we want," the island's mayor Stelios Bozikis told Greek radio. He condemned the attack, but also the reckless behaviour of tourists.
Laganas has one of Greece's most beautiful beaches, which is guarded by environmentalists as it is a nesting ground for the loggerhead sea turtle.
