MOSCOW (AP) — Another top Russian race-walker has been suspended on suspicion of doping in a case which heaps more pressure on the scandal-hit Russian team, widely considered the world’s best.

Andrei Ruzavin, 28, is suspected of “the use or attempted use by an athlete of a banned substance or banned method” and is suspended from all competitions and official training camps, the Russian Anti-Doping Agency says.

With several team members serving suspensions or bans, Ruzavin has emerged as a leading competitor in recent months, winning bronze at the race-walking World Cup in Taiwan in May.

Russian anti-doping authorities are already investigating the national race-walking training center for a spate of positive tests.

At least 17 athletes from the center have received doping bans in recent years.
