In 1934, after being offered a position in the Malaya police, and studying Malay at the
School of Oriental and African Studies, London, he went to
Kuala Lumpur as a police probationer, and trained in the police academy. He then served as a police officer in
Selangor,
Perak,
Pahang and
Johore, rising to the rank of Assistant Commissioner of Police of the
Federated Malay States in 1937. In 1942, he was imprisoned for over three years by the Japanese army as a
POW in
Changi Jail, and later at Sime Road Camp,
Singapore. While serving as Commissioner of Police he was credited with modernising and strengthening the force, and was recognised as having made a significant contribution during the Malayan Emergency to the eventual defeat of the insurgents. He oversaw the celebrations of the independence of the Federation of Malaya on 31 August 1957, describing them as "Not a bad start for a new nation". Shortly before retiring in 1958, he was awarded the
Paglima Mangku Negara. On his return to England, Carbonell worked as a business consultant. He retired in the 1960s, and died in
Frimley,
Surrey on 30 September 1993. == Personal life ==
