Colombo, June 29 (DPA) A former presidential security chief was jailed Tuesday for four years on a conviction of threatening a fellow police officer during an election rally nine years ago, a court official said.

Nihal Karunaratne, a former police deputy inspector general, was an influential figure during the 1994-2004 presidency of Chandrika Kumaratunga.

A high court in the central Kandy district found him guilty of threatening the officer in charge of a police station and interfering with the work of the police.
