The opposition People's National Congress Reform (PNCR) says the gun attack which left its general secretary Oscar Clarke hospitalised "is another example of the precarious crime situation which is facing Guyana at the moment".
Clarke, 74, was shot at least twice after bandits entered his Sophia, Greater Georgetown, home on Tuesday night.
Admitted to hospital
In a statement, the PNCR said that Clarke was admitted to the Georgetown Public Hospital Corporation (GPHC) "and is currently in a stable condition".
The GPHC in a brief statement said Clarke was suffering from gunshot wounds to the abdomen and left leg.
"His condition is considered as stable but doctors continue to monitor him. He has been placed in the High Dependency Unit," the GPHC said.
