Mexico City, Mexico (CNN) -- A leader of Mexico's Sinaloa drug cartel, Manuel Garibay Espinoza, was detained Friday in the northwestern border town of Mexicali by Baja State Police, a federal police spokesman said.
"Manuel Garibay Espinoza is in police custody and at an airport being transited to Mexico City," said Ramon Salinas, the spokesman.
Garibay led the Sinaloa cartel in Baja California and worked for both the cartel's overall leader, Joaquin "el Chapo" Guzman, and the formerly dominant Arrellano Felix cartel, which has seen several of its leaders captured in recent months, Salinas said.
Salinas said Garibay was "one of the principal faces of the cartel of Sinaloa" and had been a part of the Arellano Felix cartel since 1992.
