Animal officers are trying to find the owner of a nappy-wearing monkey which bit a member of the public in Cardiff.
The squirrel monkey, which was seen wearing a nappy, collar and lead, was spotted at a fair on Leckwith Road in the city on April 13.
The RSPCA have now issued an appeal for information after the animal bit a member of the public twice.
The man was taken to hospital to undergo tests.
Under UK law, the pet owner would not need a licence to keep a squirrel monkey.
But the RSPCA are calling on the Welsh Government to introduce a ban to prevent members of the public keeping primates as pets.

RSPCA inspector Sophie Daniels said: “We’re really keen to speak to the owner of this monkey and if anyone has any information about them, please contact us on the RSPCA's inspectorate appeal line on 0300 123 8018.
"A member of the public would not require a licence to keep a monkey like this but we’re keen to know why this monkey was in this environment and if people were being encouraged to handle the monkey.
"The member of public who was bitten subsequently went to hospital for tests, which we would encourage."
“We have spoken to those who run the fair and say they are unaware of this person."
Ros Club, RSPCA senior scientific manager, said: “Primates are highly intelligent animals with complex needs that can't be met in a home environment. However well intentioned an owner may be, they are not suitable as pets.
"We are concerned as to whether there is a growing problem in Wales of primates, like marmosets, being kept as pets. We believe the time has come for the Welsh Government to act, and want to see an outright ban on the keeping and trade of primates as pets in Wales."
