A dozen US Secret Service agents sent to Colombia to provide security for President Barack Obama at an international summit have been relieved of duty over alleged misconduct.
A caller who said he had knowledge of the situation told The Associated Press the misconduct involved prostitutes in Cartagena, site of the Summit of the Americas. A Secret Service spokesman did not dispute that.
An unnamed US official put the number of agents sent home at 12 but the Secret Service did not disclose the number of personnel involved. The incident threatened to overshadow Mr Obama's economic and trade agenda at the summit. The White House had no comment but did not dispute the allegations.
