According to the police, the thieves were able to break into the establishment, and make off with the hefty safe all within three minutes. A group of thieves broke into a popular Ninja museum in central Japan and escaped after stealing a heavy safe that contained over a million yen (around Rs 7 lakh). The burglars carried out the heist within a matter of minutes in the early hours of Monday morning, the Guardian reported. Police were called to the famous Iga-ryu Ninja Museum, located in the Japanese city of Iga, after an alarm went off once the thieves fled the scene. Law enforcement authorities found that the museum’s main office had been robbed and its entrance appeared to have been forced open with a crowbar, according to a report by BBC.
