Two members of an elite Ground Self-Defense Force unit were arrested Friday on suspicion of mugging a man in Tokyo, police said.

Hiroki Matsubara, 21, and Kazuya Iwayama, 23, both members of the 1st Airborne Brigade based in Funabashi, Chiba Prefecture, allegedly assaulted a 22-year-old man in the Roppongi district and robbed him of around ¥130,000 in cash at around 3 a.m. Friday, the police said.

The two initially asked the victim to lend them some money but beat him up after being ignored, police said.
