Former Deputy Inspector General (DIG) Vass Gunawardena, and his son Ravindu were found guilty for the abduction and murder of businessman Mohamed Siyam and sentenced to death by the Colombo High Court Trial-at-Bar.
He became the highest ranking police officer ever to be convicted for murder.
His role was only discovered when CCTV footage showed Shiyam being taken away in a vehicle driven by Gunawardena's son.
Four policemen who worked with Gunawardane were also found guilty and sentenced by the court for their involvement in the murder.
Siyam was abducted and murdered in the Dompe area on May 22 in 2012. Gunawardena was arrested in June 2013 and was remanded in custody. He was arrested just a month after being promoted as a DIG.
It was alleged that he had taken money to intervene in a transaction between the deceased Shiyam and another businessman. Gunawardena was known for his work to combat underworld operations in the country.
