Triple Nine is an English language television police procedural telecast on what was then the Television Corporation of Singapore's Channel 5 from 1995 to 1999. The station's earliest attempt in an action-based drama series, it revolved around the lives of a group of police officers, namely Inspector Mike Chin, Inspector Elaine Tay, and Sergeant Alan Leong from the Special Investigation Section of the Criminal Investigation Department. The cast changed in subsequent seasons, notably with the inclusion of Inspector Sean Han, Inspector Herbert de Souza, and Sergeant Yeo Lay Kim from the third season, and Sergeant Sarah Chan from the 4th season. Season 2 was written by Amos Kwok. The first season was also dubbed into Chinese and aired on Channel 8 in 1996.
