A woman who says she was the prostitute who triggered the US secret service scandal in Colombia said that the agents involved were "idiots" for letting it happen, and declared that if she were a spy and sensitive information was available, she could have easily obtained it.

The woman said she spent five hours in a Cartagena, Colombia, hotel room with an agent, and while she barely got cab fare out of him, she could have gotten information that would have compromised the security of US president Barack Obama if the agent had any. "Totally," she replied when asked.

"The man slept all night," said the woman, who was identified by her lawyer as Dania Londono Suarez. "If I had wanted to, I could have gone through all his documents, his wallet, his suitcase."

She said in the 90-minute interview with Colombia's W Radio that no US investigator had been in touch with her, although reporters descended on her home a week after the incident when a taxi driver led them to it.
