Police have been told two alleged drug kingpins, who are wanted by authorities, may have come to harm whilst living abroad.
Officers believe brothers, James and Barry Gillespie, play a huge role in Glasgow's underworld.
However, the brother's family have indicated the pair were harmed after escaping to another country. It has previously been alleged that the Gillespies, from Rutherglen, were executed in Brazil following a fall out with gangsters.
