It does happen, like this is what was done to an undercover DEA agent where he was tortured by a cartel leader for 30 hours because he cost the cartel a lot of money:
Kiki was held at 881 Lope de Vega in Guadalajara; this house was owned by Rafael Caro Quintero. Kiki was held against his will at this location for about three days. During this time Kiki was subjected to numerous torture techniques for over 30 hours. Quintero and others brutally assaulted Kiki over and over again. They crushed his skull, jaw, nose, and cheekbones by beating him with a combination of fists and a tire iron. They broke his ribs with numerous assaults to his mid-section. They were so brutal in their attack that they even drilled a hole in his head, and if that was not enough, they also tortured him with a cattle prod.
The torture that Kiki Camarena underwent was so intense that he passed out from the pain and almost died a few times during these torture sessions. Quintero was such a psychopath about the tortures that he ordered a cartel doctor to keep Kiki alive. “At that point, he administered lidocaine into his heart to keep him alert and awake during the torture,” (Jeunesse). Due to his numerous wounds from the torture, eventually Kiki could no longer be kept alive, and he died on February 9th, 1985.

Nigeria is famous for it's corruption and Bangladesh also has problems with organized crime, so all it would take is some psycho organized crime leader who blamed Saleh for costing him money or who felt financially threatened by him. This for instance seems threatening in Nigeria:
A spokesman for the ruling party, All Progressives Congress, Joe Igbokwe hinted at the ban in a Facebook post on August 2019: “Instead of partnering with govt on BRT, you invested “5.3 million dollars” in okada business and expect that Lagos state will allow you jeopardise its muliti-billion (sic) naira mass transit investments.”

Now Saleh won't be allowed to jeopardise large mass transit investments and others in the Lagos okada business can take it as a warning.
