Coca-Cola's largest Mexican bottler says it had received threats before attackers burned four of its delivery trucks in an area of southern Mexico known for drug gang turf battles.

The Femsa company said in a statement late Tuesday that it closed a distribution plant in the southern state of Guerrero last Wednesday after receiving threats.

Femsa did not specify the nature of those threats, but said they were directed at delivery personnel.

The Guerrero state prosecutor's office said the motive in the attack in the township of Arcelia is under investigation.

While local companies are frequent targets for gang extortion, attacks on multinational firms are rarer.

In 2012, the Knights Templar cartel in neighboring Michoacan state burned five warehouses and dozens of vehicles owned by a Mexican subsidiary of PespsiCo.
