Parents sue university tennis club over son's binge-drinking death

The parents of a 21-year-old who died during a drinking binge with his university tennis club in Japan are suing fellow student members over his death.

The couple filed a lawsuit on Wednesday against 21 former members of the club at the prestigious Tokyo University, demanding compensation of 170 million yen ($1.36 million).

"There is no greater sorrow than losing your own child," tearful father Toshihiko Takahashi told a news conference after filing the lawsuit at Tokyo District Court on Wednesday.
