LIBERIAN smugglers allegedly used the presidential motorcade to bring about 300 kilograms of marijuana into the country from Sierra Leone.

Anthony Souh, director of Liberia's Drug Enforcement Agency, said the head of the presidential motorcade, Perry Dolo, and three others were being questioned.

Dolo was arrested along with another Liberian official, as well as a Guinean and a Sierra Leonean over the weekend after crossing from neighbouring Sierra Leone via the Bo-Waterside border.

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

Souh said that Dolo had taken the car on his day off.

Marijuana smuggling has become a growing problem in Liberia.
