Slovenian police say a man has died upon being arrested after he hijacked a public bus in the capital Ljubljana.

Senior police official Stojan Belsak said Friday that an autopsy will determine the cause of death of the 48-year-old man from the central city of Kranj.

The man on Thursday was carrying a screwdriver and threatened to kill the bus driver and seven passengers unless the bus was directed toward a highway. Belsak says police intercepted the bus before it reached the highway. Police say they used tear gas to stop the man from escaping and they then handcuffed him. No shots were apparently fired.

Belsak says the man is known to have had psychological problems.
