Based in Tiger Bay in Cardiff, Sangoe's professional career spanned from 1956 to 1960 and he held the Welsh light heavyweight title from 1958 to 1960, successfully defending it on two occasions.
[1] Sangoe turned professional in 1956, under the management of Eddie Dumazel, and on 16 July he faced his first pro opponent, Danny Wall at Maindy Stadium in Cardiff.
[1] Sangoe followed these victories with successes over Ken Gardener, Colin Strauch and Dennis Lockton, before losing to Ron Redrup on points in June 1957.
Trigg started the stronger with cleaner punching, but his stamina began to drain as the fight progressed which allowed Sangoe the upper hand in the later rounds.
[3] After the Turpin fight, Sangoe took a five-month break before lining up against Chic Calderwood at Earls Court Empress Hall in Kensington on 12 January 1959.
[3] Sangoe followed the Calderwood match with a win over Ted Williams, but then he was lined up against ex-British Lightheavyweight champion Ron Barton who took the eight round fight on points.
He lost on points to Gerry McNally at Oxford in April and then he was stopped by Jack Whittaker on 27 June at Coney Beach Arena in Porthcawl.
[4] A great gym-fighter, with an excellent jab and good ring movement, Sangoe suffered from nerves on fight night, which Jones believes prevented him from reaching his full potential.
[4] At Benny Jacob's gym, Sangoe would often spar with the likes of Erskine, Phil Edwards and on occasional visits, Brian Curvis and dealt with them comfortably.
[4] When American heavyweight fighter Mike DeJohn came to Wales in 1960 to face Dick Richardson, he stayed in Cardiff and sparred with Sangoe.
[5] The South Wales Echo reported at the time that Sangoe had initially been taken to Bute Street police station, before being transferred to the hospital where he was pronounced dead.
