Cong An Ha Noi

Establishment and breakthrough (1956–2002)

In 1954, Minister of Public Security Trần Quốc Hoàn directed then-Hanoi City Public Security Director Nguyễn Văn Long to establish a football team known as Công An Hà Nội Football Club. Founded on 10 October 1956, perhaps only after the military's Thể Công, and became known as the "capital's representative" by the People's Committee of Hanoi. When first established, the CAHN was under the leadership of Lê Viễn, an official in charge of sports within the Ministry of Public Security, and Hoàng Nghĩa Đường, a former boxing champion of Indochina and a member of the Coordination Department of Hanoi Public Security. They used their political influence to request special permission from the Ministry of Public Security to take over almost the entire Hoàng Diệu Football Club. This team, whose players had previously been at a military police team run by the French colonial administration, was the strongest in Hanoi at that time. Its lineup included goalkeepers Nghĩa and A Loóc, as well as players Bùi Nghẽn, Lưu Đình Tòng, Nguyễn Huy Luyến, Nguyễn Thưởng, Nguyễn Văn Thìn, Bùi Hợi, Vũ Hợi, Tuất, and Phú Tí. The team was supplemented with public security officers interested in football and talented young Hanoians. In the early stages, there were individuals such as Phan Đức Âu, Nguyễn Mạnh Cường, and in the following group, there were Đài "gôn", Tô Hiền, Tô Giới Pháp, Xuân "gôn", Du "cò", Sơn "min", Đức "khựa", Độ "trây", Thọ "gáo", Thái "si", Thịnh "cơm", Hạc "phệ", Thành A., Ngọc "tráp", and Dư "còng".

During the early days of restored peace, the matches of Công An Hà Nội versus Thể Công, as well as their matches with other teams at the Septo Field (which was renamed Hàng Đẫy Stadium in 1958), served as a real source of encouragement for the nation's rebuilding efforts after the extraordinary anti-French colonial period.

By the late 1960s and early 1970s, the Hà Nội city prioritized adding players to the club from various sources. There were internally trained players like Tô Quang Nhạ, who later became the captain. Players transferred from Thanh Niên Hà Nội, such as Quang B, Đặng "cóc", Hai "voi", Cường Học, Pháp "ngớ", Điệp "lùn", and Chi "tơ". Players coming from abroad, including Thành C. and Hiển "Coóc" (Từ Như Hiển). From the Thể Công team, there were Duy Lễ and Nghị “chớp”, and from the training school, there was Hiếu "trâu".

In 1957, just one year after its establishment, Công An Hà Nội defeated Thể Công 2–0 in the finals of the Northern Region A League Championship, asserting its position in the football community of Northern Vietnam.

The second half of the 90s of the 20th century can be said to be an unfortunate period for the team when with a relatively equal lineup of players, but the team is more known for its betting scandals and borrowing points. than achievements on the field. In 1992, the team performed poorly and had to be relegated to A1. In the 1995 season, the team again won the right to be promoted to the Major League (currently V.League 1).

Over the years, the team has contributed many generations of players to the national team of the Public Security sector, competing against public security teams from other countries within socialist blocs, as well as representing Hanoi and Vietnam in various international tournaments.

Dissolution (2002–2007)

In the period of changing the mechanism in how to make football, a football team of players on the staff of the Public Security could not exist. In 2002, the team was dissolved and sold their participation slot to Vietnam Airlines at 2003 V-League. After the 2003 tournament, the Vietnam Airlines was dissolved and sold their spot in the V-League to ACB Sports Joint Stock Company, the owner of Hanoi ACB. This club also accepted eight players from Vietnam Airlines The rest of the players were transferred to play Vietnamese National Football First Division with Hòa Phát Hà Nội.

Re-establishment as Công An Nhân Dân (2008–2021)

On 7 April 2008, Lieutenant General Nguyễn Khánh Toàn, the then-Deputy Minister of Public Security (Vietnam) signed the Decision No. 375 to establish the Công An Nhân Dân Football Club, a club belonging to the Vietnam People's Public Security. After several playing in lower divisions of Vietnamese football, Công An Nhân Dân won the 2022 V.League 2 and promoted to the V.League 1 for the first time since their formation.
