Pengiran Jaya bin Pengiran Haji Rajid was born in Brunei in 1925 and began his service in the police force on 24 September 1945. In 1955, he attended a six-month training course for junior police officers in
London. The following year, on 1 September, he was promoted to assistant superintendent. In 1957, during the official opening of
Brunei Airport and its new terminal building, Pengiran Jaya, then an inspector, led the police honour guard. This event marked the first time the force appeared in their new uniforms of black pants and white shirts, and it was attended by
Sultan Omar Ali Saifuddien III,
British Resident John Orman Gilbert, and Abell. Additionally, Pengiran Jaya played a key role in welcoming
Prince Philip, Duke of Edinburgh, during his 1959 visit to Brunei, leading the police band and the Royal Brunei Police honour guard. In January 1961, Pengiran Jaya was promoted to superintendent. To further his career, he left for Scotland on 27 September to attend a senior police officer training course at the
Tulliallan Castle Police College near
Edinburgh. In 1964, he was part of a delegation of three Bruneian government officials who traveled to Singapore and
Kuala Lumpur. The purpose of the trip was to observe the identity card registration procedures, including visits to
immigration offices in both cities and the main identity card registrar's office in
Petaling Jaya. This visit was part of the preparations for the anticipated introduction of the
identity card system in Brunei. Later that year, on 22 November, he traveled to London carrying two bags filled with 50 pounds of confidential documents, as part of the delegation accompanying the sultan for talks on constitutional reforms. In December 1969, Pengiran Jaya issued a public warning against the use of fireworks during
Hari Raya,
Christmas, and
Chinese New Year, reminding citizens that the importation and sale of fireworks were illegal and offenders could face prosecution under Brunei's emergency laws. As the first local Bruneian to serve as Commissioner of Police in 1975, Pengiran Jaya's leadership marked a significant milestone for the Brunei Police Force. This transition was a major shift, as the Commissioner is responsible for steering and planning the force's development. Under his command, Pengiran Jaya focused on strengthening the administration and ensuring that the police force was efficient and adaptable to changes in the environment. He was committed to establishing a professional and competent force, dedicated to serving the interests of both the people and the state of Brunei. His leadership was crucial in addressing various challenges, enhancing public safety, and improving the overall administration and effectiveness of the police force. In early January 1977, the Royal Brunei Marine Police launched a new fast patrol boat, "PDB
Sejahtera," in a ceremony held in
Muara, where Pengiran Jaya, along with senior police officers and their families, attended. After serving for many years, he retired from the police force in 1983, with
Pengiran Umar succeeding him. == Later life and death ==
