Mozambican officials say they are investigating the abduction of a wealthy businessman who had been accused by the U.S. government of being an international drug trafficker.

Deputy Interior Minister Jose Mandra said Friday on Radio Mozambique that police were trying to trace Mohamed Bachir Suleman.

Officials and witnesses say Suleman was kidnapped on Wednesday by several men with assault rifles in the parking lot of a shopping mall that he owns in the Mozambican capital, Maputo. Officials say they have not received any ransom demands.

In 2010, U.S. President Barack Obama put Suleman on a U.S. list of specially designated narcotics traffickers and barred Americans from doing business with him. Suleman denied he was involved in drug trafficking.
