Another miner has been murdered in the increasingly violence-prone interior.
Police said that George Cardario, 51, of Middle Mazaruni, died at around 03:30 hrs yesterday after he was stabbed in the abdomen during an argument with another man.
The suspect has been arrested and is in police custody assisting with the investigations.
Meanwhile, police are still investigating the shooting on Saturday of 26-year-old Christopher Mann at Arakaka, North West District.
Mann, an administrator of Gold Mines Corporation and of Bon Fin, Brazil, was reportedly wounded when two men invaded the camp and demanded gold.
A scuffle reportedly ensued during which he was shot.
Police said the robbers also relieved an armed security guard of a .38 revolver and six rounds of ammunition.
The injured man was taken to the Matthews Ridge Hospital before being transported to a city hospital.
Yesterday, a sister of the wounded man said that he is in a stable condition but declined further comment.
Last Wednesday, dredge operator Gavin Mc Neil was shot dead at his Mc Doom, East Bank Demerara home by a group of young bandits who also terrorized and robbed his family.
