North Korean defector spends six hours walking around heavily guarded border unnoticed

Embarrassment for South Korea's military after guards fail to heed alarms despite man being picked up by five sets of CCTV cameras

South Korea's military is facing criticism over security lapses along the country's heavily armed border with North Korea after a man was able to cross into the South despite being spotted multiple times by surveillance cameras.

The man, wearing a wetsuit and flippers, reportedly swam to South Korea in the early hours of 16 February, but evaded capture for more than six hours, according to the Yonhap news agency.
