While fights on Greek islands are often started by people drinking too much liquor and getting into drunken battles, two groups of French tourists in Crete engaged in a violent brawl over two cans of an energy drink, reports said.

It happened in Hersonissos in the northern part of the island after an argument over the drinks – the brand wasn't identified – said the local news website  www.cretalive.gr.

They apparently had enough energy already to tear into each other, a 24-year-old accused of attacking another with a broken bottle, leaving him with serious injuries after the shouting began.

One of the groups had bought the drinks fom a supermarket along with a bottle of vodka after bars closed at midnight under new measures designed to prevent the spread of COVID-19.

The suspect denied charges of assault, claiming that he had intervened to stop the argument from escalating but is due to face trial Aug. 24.

Greece opened to tourists in July in a bid to get the economy going somewhat again after a lockdown March 23, gradually lifted week-by-week starting May 4 but hasn't seen the numbers expected, people fearful to fly or travel so far yet.
