Albanian police have arrested four villagers accused of staging a botched armed robbery on a bus in the country's mountainous south that killed one passenger and injured another.

A police statement Wednesday said the suspects, aged between 20 and 32, were under the influence of marijuana during Monday's attack which they had planned a day earlier.

The bus, heading from Athens, Greece, to the Albanian capital of Tirana with 21 passengers on board, was attacked on a highway near the city of Tepelene.

A 25-year-old passenger died in the hospital from gunshot wounds and a 19-year-old woman was treated for cuts from broken glass.

Police said that the suspects, who came from a nearby village, could be jailed for life.
