Police seized 19,000 sea turtle eggs off the coast of Malaysia in the early hours of July 16 in a special operation to hobble a major smuggling syndicate, the Straits Times of Singapore reports.

Malaysian Marine Police in the state of Sabah got a tip-off that smugglers were in the area, so they sent three police vessels to intercept them. When the police vessels came into view of the suspected smugglers’ four wooden boats, a chase ensued.

“The team spotted the pump boats around 1:30 a.m., and a chase ensued,” Sabah Marine Police Chief Assistant Commissioner Mohamad Madun told Malaysia’s New Straits Times. “After a brief pursuit at sea, our men managed to intercept the boats.”

On board they found sacks containing thousands of eggs, worth about $7,400, according to the Straits Times. They detained four Filipinos on suspicion of smuggling and another eight suspected illegal immigrants.

The four Filipinos, if convicted, face up to five years in prison or a $12,300 fine, according to the New Straits Times. For comparison, the average annual income in the Philippines, where the suspected smugglers are from, is $2,700.

In Malaysia, where sea turtle eggs are considered a delicacy, each state makes its own laws about turtle egg collection and consumption. In Sabah, all sea turtles and their eggs are protected, but in many states, the legislation falls short, according to WWF-Malaysia. The organization is calling for a national ban on sea turtle egg sales and consumption.

IVORY KINGPIN: In what activists call the biggest ivory trafficking case in Kenya’s history, Feisal Mohammed Ali was found guilty of dealing in and illegally possessing ivory. He was sentenced to 20 years in jail and fined nearly $200,000, according to The Star. He and four others were accused of possessing 2.3 tons pounds (2.2 metric tons) of ivory in 2014—representative of 157 elephant deaths. After the ivory seizure, Mohammed fled to Tanzania, where he remained a fugitive until he was arrested by Interpol almost seven months later. The four others were acquitted.
