Police in Bryansk say an 18-month-old child was swept into the underground municipal sewage system when a sidewalk collapsed because of a ruptured pipe.
The mother, a 26-year-old policeman's wife, was pushing the child in a stroller when the ground caved in underneath them. Police say the woman was rescued, but the child was swept away by the current into a collecting tank for the sewage system and was presumed dead.
Investigators say they are working to determine the cause of Sunday's accident, but suspect faulty construction of the system may be to blame.
