The Osaka Police Department has enlisted the 'Robocop' to stop the perverts threatening women.
"Robocop is a hammer of justice to molesters threatening women," the police said on its official site.
The police has collaborated with West Japan Railway Company and developed the Robocop - a man posing as a cyborg crime-fighter.
Interestingly, the robot has the right to arrest citizens who are found breaking the laws.
The robot is also assigned the duty of warning travellers not to leave their belongings and luggage in the train carriages, the Mirror reported.
In addition, it will caution drivers not to leave possessions on view in cars.
