An official watchdog in Germany has told parents to destroy a talking doll called Cayla because its smart technology can reveal personal data.
The warning was issued by the Federal Network Agency (Bundesnetzagentur), which oversees telecommunications.
Researchers say hackers can use an unsecure bluetooth device embedded in the toy to listen and talk to the child playing with it.
But the UK Toy Retailers Association said Cayla "offers no special risk".
In a statement sent to the BBC, the TRA also said "there is no reason for alarm".
