A man was killed and another was seriously injured after they were attacked by six unidentified suspects while driving in the capital’s Russey Keo district on Tuesday night.

Soeun San, 22, a chef, sustained a broken left wrist and 20 stitches to his head, while Chan Ny, 26, a waiter, succumbed to his injuries.

The National Police said after drinking near a market in the district’s Tuol Sangke II commune, the duo were travelling on Mong Rithy street to a karaoke parlour when they encountered six men who were crossing the street.

When the two failed to pause, the suspects shouted insults, then chased and beat them until they fell off their motorbike.

The six kept battering them before fleeing the scene. Keo Chantha, Tuol Sangke II commune police chief, said the search for the six suspects is proceeding.
