Hong Kong's first Chinese police commissioner, Li Kwan-ha, died on Monday after collapsing at his home in Pok Fu Lam.
He was certified dead after being rushed to Queen Mary Hospital. He was 80 years old.
Li was appointed to head the force in 1989 and retired in 1994.
He controversially took a job with Cheung Kong Holdings while he was still on pre-retirement leave.
The Chief Executive, CY Leung, expressed his sorrow over Li’s death and conveyed his condolences to Li's family.
The current Commissioner of Police, Stephen Lo, said he was deeply saddened by Li’s death.
"Mr Li was the first Chinese Commissioner of Police and was an outstanding leader. We expressed profound sadness at his death. I and my colleagues within the Hong Kong Police Force convey our deepest condolences to his family," Lo said in a statement.
