Three men have been arrested by Amalgamated Security Services following the theft of equipment from Heritage Petroleum Company Limited.
The company says the heavy oil equipment was stolen from the forest reserve area.
A statement says that around 10.30 pm on Wednesday, security officers were on mobile patrol when they observed a truck carrying equipment.
They stopped the vehicle, questioned the driver and its two occupants and examined its contents which were 19 electrical motors and one generator.
The Heritage Petroleum Company Limited says it's investigating another act of sabotage.
The company says an upper valve was stolen at well #912 in Palo Seco, resulting in a mist of oil being sprayed onto a remote grassy area with less than three barrels of oil leaked.
The well was discovered today at 11.30 a.m. by HSE personnel and a response team was immediately dispatched.
A new upper valve was installed to contain the well pressure and prevent further leakage.
