Chief Superintendent Hark

He was a detective in the Central Police Department, but was involved in making counterfeit money with the Over Heaven society.
His subordinate, Sung Tse-Kit, was aware of this and was investigating, but Lau Ming Wa found out and instructed the brothers Senior Dumb and Junior Dumb to kill Kit.
After this, Hark was threatened by Lau to falsify autopsy results in cases involving the Web.
