Several warning shots have been fired by police officers trying to recapture a chimpanzee which had escaped from its enclosure at Belfast Zoo.
Police said officers had consulted with a vet and zoo management before firing the shots near nine-year-old chimp Phoebe.
The zoo had to be closed for about an hour after Phoebe used a log in her enclosure to climb over a wall.
She has since been recaptured and returned to the ape-house unharmed.
A spokesman for the zoo said the log had been removed from the animal's enclosure.
"We want to thank the PSNI who were called as a precautionary measure for their help and thank those visitors in the zoo for their co-operation in remaining indoors while the effort was under way," he said.
