Drug Enforcement Agency investigators in Liberia say they are questioning the head of the presidential motorcade and three others for allegedly using the convoy to smuggle more than 297 kilograms (654 pounds) of marijuana into Liberia from neighboring Sierra Leone.

Anthony Souh, director of the DEA office, named the motorcade commander as Perry Dolo. He was arrested along with another Liberian official, as well as a Guinean and a Sierra Leonean over the weekend after crossing from Sierra Leone via the Bo-Waterside border.

He named the vehicle used as "Escort 1," the jeep that normally leads the president's convoy.

Souh told The Associated Press that Dolo had taken the car on his day off.

Marijuana smuggling has become a growing problem in Liberia.
