Guka is smarter than that. If he was involved,no single cent would have been recovered. Even the G4S vehicle could have disappeared forever. Some of it's parts could actually be in his bijuti as we speak.
Me thinks he is planning one. My guess would be the heist will be in Tanzania and it will not be in the news. The Tanzanian government will be so embarrased they will not be willing to talk about it. Unknown number of robbers walked into a bank on an unknown day at an unknown time and walked away with an unknown amount of cash in foreign currency.... Surely no one would want such a headline!!!!
Never count on making a good sale. Have the purchase price be so attractive that even a mediocre sale gives good returns.
