Today, Spanish police have arrested Peruvian Dr. Walter Viru under the suspicion of running a doping ring. Dr. Viru has collaborated in the past with Eufemiano Fuentes, who was arrested over three years ago as part of Operacion Puerto. Alongside Dr. Viru, a dozen people were arrested in Spain; Barcelona, Valencia, Granada, and Murcia, including several doctors and two pharmacists. Reportedly, they trafficked EPO, CERA, and growth hormone. Several cyclists’ homes were also raided. A raid at Dr. Viru’s clinic in Valencia found banned substances as well as documentation proving that Viru was indeed involved in the ring. Investigations are ongoing, stay tuned for details.
