China has installed a silent alarm system inside every house in a border town as part of its strengthened crackdown on fugitives from North Korea, a report said on Friday.
The system is designed to let residents secretly send a signal to police if North Korean escapees come to their houses and ask for help, South Korea’s Yonhap news agency said.
It can transmit dialogue between the owner of a house and visitors, and Chinese authorities plan to expand it into other areas bordering the North, the agency said.
“If you push the red button on the wall, a signal goes directly to a police station,” Yonhap quoted one man as saying.
The man said he saw the device during a recent trip to his relative in the Yanbian border area in northeastern Jilin province.
Yonhap said China had stepped up a crackdown in border areas since South Korea criticised its repatriation of dozens of North Korean refugees in February and this month.
