Philippine National Police chief Gen. Rodolfo Azurin Jr., on Monday ordered all police commanders to intensify its crackdown on guerrilla operations of online sabong or e-sabong in the country.

This comes after reports that some online sabong sites continue to run illegally amid a presidential directive to put a stop on the online gambling activity.

"There was already a presidential order (former president Rodrigo Duterte) to stop all e-sabong activities. But we monitored that there were guerrilla operations of e-sabong until now," Azurin said.

Then President Rodrigo Duterte issued the order to stop all online sabong operations after the controversial abductions of at least 34 cockfighting players who all remain missing until now.

While the major operators of e-sabong already stopped their operations, there were some small groups and individuals that continue to use the online platform for cockfighting betting.

Azurin said that he also received reports that the guerrilla online sabong operations have been catering to overseas Filipino workers.
