He had to perform twice for an African festival at the huge Forest National in Brussels. His manager for those event was Coco Rubenga. Nyoka Longo already received the money of the first day, but he was bored at the place he was staying so he decided to go the office with his friend to get the money of the second. When arriving at the office, a employee explained that the manager already withdrawed the money. It made Nyoka Longo furious, he called Coco Rubenga and they started agruing. Coco Rubenga was really mad and decided to finish Nyoka Longo by snitching him about ngulu's to the police. He knew about Zaiko's documents and that atalaku Nono Monzuluku didn't travel with his own passeport.
Nyoka Longo left Nono behind for Zenith as punishment. It made Zaiko-fanatics mad, because it was Zaiko's first show at a mythic hall and Nono being the first atalaku in the history of Congolese music but being absent. So to mad it up, Nyoka mae him travel with a passeport of a ngulu, who didn't make it on the list. Nono couldn't travel on his own passeport, because it was used by somebody else. Belgian police did their investigation in Belgium and Kinshasa and contacted the real Luisa Alberto. After that they arrested all bandmembers to question them. Nono hadn't any choice to admit since that the police was insisting on him, him being scared and not wanting to get deported. This made Nyoka Longo being arrested for the ngulu-affaire and spending like 4 or 5 months in jail. Compared to Wemba's arrestation there was less noise about it and the governement didn't support him which they did with Wemba.
Zaiko's fanatics were mad at Nono, claiming that Koffi paid him money to betray Nyoka Longo which wasn't true. Months later Nyoka Longo would explain the real story about it during a press-conference back in 2004.
There used to be a video on youtube about Nono explaining what went on. But INA Congo's channel with that video got deleted. He talked about the way they were arrested during Ado Yuhe's show where he was invited 2 years ago.
