Anti-terrorist bomb squad experts were called to a post office in the northwest of Russia to make safe a package from which a strange ticking sound was coming, local police said on Monday
They found a vibrator.
The incident took place at Petrozavodsk in the republic of Karelia and followed a call from a postal worker who had identified a suspect package, a police spokeswoman told AFP by phone.
"The post building was ringed by the security forces and people were evacuated," she said.
"In the package the bomb squad found a vibrator."
The sex toy had apparently been turned on "by accident".
