World steeplechase champion Marta Dominguez, who is suspected of trafficking in performance-enhancing drugs, has insisted she's innocent after being questioned in court over the allegations.
The 35-year-old, who won 3,000 metre steeplechase gold in Berlin in 2009 after taking silver in the 5,000 metre in 2003 and 2001, arrived at the court accompanied by her husband and a lawyer.
She said she was implicated in the investigation into sports doping because of telephone wiretaps without giving further information.
Dominguez was one of 14 people detained by police on December the 9th as part of the investigation into sports doping dubbed "Operation Greyhound".
Six of the 14 detained suspects were charged with public health offences and trafficking in illegal substances, including Dominguez' coach Cezar Perez.
Dominguez has been suspended as one of the four vice presidents of Spain's athletics federation while the investigation is underway.
