Russian media reported on Tuesday the bodies of the eight people who took part in an unauthorised group tour of Moscow’s sewers have been found by authorities.
“As of today, all eight members of the group have been found dead. The search operation is over,” a spokesman for the city’s emergency services told TASS.
Water levels in the sewers rose quickly after a torrential downpour on Sunday and the victims couldn’t flee to the surface.
The group was reported to have been exploring the underground Neglinka river, a tributary of the Moskva River.

The offences carry a maximum sentence of 10 years in prison.
