MOSCOW, January 16. /TASS/. Russia’s Investigative Committee has found evidence proving a gas leak triggered an explosion in a residential building in the southern Russian town of Shakhty, but no residues of explosive devices were spotted at the scene, the committee’s Spokeswoman Svetlana Petrenko told reporters on Wednesday.
"Staff members of the Investigative Committee’s Main Forensics Department did not find any residues of explosives while searching the crime scene with a gas analyzer. Chemical examinations are to be done on collected wipe samples," she said.
Investigators established that the explosion epicenter was located in Flat 72 where a 66-year-old woman had lived.
"A gas stove was confiscated from the flat. The gas cock valve was in the position of ‘open’ at the moment of inspection," Petrenko said.
