Did you go to the police after, maybe someone saw something and these guys can be found with any details provided to them.
OP said they were arrested but sadly how many more can come back? It's such easy money for them that they obviously have no qualms about ruining people in their own country. Is it legal to carry a weapon in Nigeria? In France, the president asked people to bring them back to the police station (even their grandfather's old rifles), obviously the criminals didn't do it, as you might expect...
