Mexican police are providing stepped-up security for a PepsiCo subsidiary targeted by firebombing attacks over the weekend.
A spokesman for western Michoacan state says about 100 police are guarding the distribution centers of Sabritas, a Mexican snack company owned by PepsiCo.
Spokesman Julio Hernandez said Tuesday it appears a drug gang was involved in the attacks that burned dozens of Sabritas delivery trucks and damaged buildings at five distribution centers in Michoacan and the neighboring state of Guanajuato.
Guanajuato state prosecutors said they detained four alleged members of the Knights Templar cartel in connection with the attacks.
Prosecutor Carlos Zamarripa says one suspect suggested the company was attacked as part of an extortion scheme, but company officials say they know of no demands for protection payments.
