Oscar winner Benicio Del Toro has written to Puerto Rico Governor Luis Fortuno urging him to halt the construction of a massive monkey-breeding facility in Guayama.

The Traffic star has discovered the facility will be run by Bioculture, a company that supplies primates to laboratories.

According to investigations carried out by animal rights group People for the Ethical Treatment of Animals (PETA), the company plans to capture monkeys from their homes in Mauritius, hold them captive in Puerto Rico, and sell thousands of their babies for use in painful and deadly experiments.

Angry Del Toro writes, "I am disappointed to learn from my friends at PETA that a company called Bioculture is proposing to build a large monkey facility in Guayama... Won't you please use your influence as governor and stop this from happening on our beautiful island? Most Puerto Ricans are strongly opposed to Bioculture's plans. Please don't allow Puerto Rico to be associated with a facility that profits from extreme animal abuse."

PETA bosses have already staged a major protest against Bioculture in Guayama, which included the town's mayor, Glorimari Jaime.
