Carlos Henrique de Senna Fernandes Basto (27 March 1890 – 31 August 1944), also known as Charles Henrique de Basto, was a Macanese businessman and member of the Hong Kong Sanitary Board.
His family was prominent among the Portuguese community in Hong Kong and Macau.
[4] He was uncontested elected to the Sanitary Board in October 1932 during the period when his younger brother, the incumbent R. A. de Castro Basto, left Hong Kong.
The investigators were able to prove that bridge problems in his possession were in fact coded messages describing Japanese troop movements.
Basto maintained his innocence to the last, but he was found guilty at a mass trial on August 29, 1944, and executed two days later.
