CARACAS (AFP) Venezuelan world lightweight boxing champion Edwin Valero has been arrested on suspicion of murdering his wife, police said Sunday. At 5:30 in the morning, the boxer came down to the hotel reception and told security personnel what he had done in his room, police commissioner Wilmer Flores told journalists. When guards went up to the room in the hotel in the northern town of Valencia they found the body of the boxers 20-year-old wife, Jennifer Carolina Viera de Valero, who had reportedly been stabbed several times. Valero, 28, who has been detained for questioning by police following his initial confession, has made a first statement and will go before a prosecutor soon, Flores said. Valero had already been arrested at the end of March for suspected aggression towards his wife and had spent time subsequently at a psychiatric clinic. He was also accused of assaulting his wife and sister in 2007. Unbeaten in 27 fights, knockout artist Valero was the WBC lightweight champion before stating his intention in February to go up a division. The World Boxing Council lists Valero as champion in recess, with the current lightweight title held by Mexicos Humberto Soto following Valeros decision to step up in weight. After beating Colombian Antonio Pitalua to claim the lightweight title in April 2009, Valero said he would consider stepping up to welterweight to take on champion Filipino Manny Pacquiao.
