Russian accused of running cocaine ring arrested in Germany

It sounds like a thriller: nearly half a ton of cocaine was hidden in bags at the Russian Embassy's school in Buenos Aires before being loaded on a Russian government plane bound for Moscow.

Yet that's exactly what happened in a recent sting run by Russia and Argentina to nab a drug ring.

Officials said Friday that the alleged ring lord, Andrei Kovalchuk, was arrested in Germany, but controversy is still swirling around the drug bust.

Russian and Argentine officials say they pooled efforts to catch the drug smugglers after at least 12 bags with cocaine with a street value of about $61 million were found at a Russian Embassy school in the Argentine capital.
