Russia asks for joint doping investigation with WADA

MOSCOW — Russian law enforcement officials have asked the World Anti-Doping Agency to join its investigation into new information about doping cases.

WADA said Friday it had obtained a database of all drug-test data from the Moscow laboratory from 2012-15, which could back up allegations by the lab’s then-director Grigory Rodchenkov of a vast doping conspiracy.

Russian Investigative Committee spokeswoman Svetlana Petrenko says the body is “ready for co-operation” with WADA and has sent an official request.

The Russian request comes a week after it claimed to have foiled attempts to obtain the database.
