[6] Prime Minister Henck Arron refused to recognise them and arrested the ringleaders, who were to go to trial on 26 February 1980.

[8] On 25 February 1980, 16 non-commissioned officers of the army deposed the government, and set up a military dictatorship, led by sergeant Desi Bouterse.

A trial followed, in which the lawyers John Baboeram, Eddy Hoost, and Harold Riedewald argued that the counter-coup from Rambocus could not be unlawful, because the Bouterse regime itself had come to power in a non-legitimate way.

[9][20] On the night of 7 to 8 December 1982, various people were captured by the soldiers of Bouterse and taken to Fort Zeelandia, among them the lawyers Baboeram, Gonçalves, Hoost, and Riedewald.

[3] On 23 March 2012, Ruben Rozendaal, also suspect in the trial of the December murders, declared under oath to the court martial that Bouterse had personally killed Rambocus and Cyrill Daal at the time.
