Taiwan prosecutors investigating an alleged breach of military security have questioned a Japanese man and 10 Taiwanese over a visit to a facility where Apache attack helicopters are based.
The Central News Agency and other local media said the prosecutors summoned 11 people for questioning Sunday about their visit last week to a restricted military base in Taoyuan, northern Taiwan.
The group was escorted by Lt. Col. Lao Nai-cheng, the head information security officer at the military facility.
Lao, a pilot-instructor trained in the United States to fly Apache helicopters, reportedly took a group of 20 people to the base last week.
The visit came to light when one of the visitors, an entertainer named Janet Lee, posted photographs of the visit on social media.
One of the photographs showed her sitting at the controls of an Apache, with the instrument panel clearly visible. Another photo showed her husband wearing a pilot's helmet inside the cockpit.
Lao was initially reprimanded by his superiors for what he did but later received harsher punishment and was removed from his post following a public outcry.
The Taoyuan District Prosecutor's Office is investigating the case.
Investigators have also learned that Lao wore a helicopter pilot's helmet and full flight suit to a Halloween party last October. Lao's wife hosted the Halloween party and most of the guests joined the controversial visit to the Taoyuan base last week, according to media reports.
