The Philippines plans to put cops in casinos to monitor other cops in casinos following a police superintendent’s alleged involvement in the kidnap and murder of a local junket operator.

Last week, Philippines National Police (PNP) officers engaged in a shootout with members of a gang suspected of carrying out the kidnapping and murder of Oscar/Carlos Tan, a junket operator working out of Manila’s casinos. Among the gang members killed in the shootout were three current and former PNP officers.

A fourth officer surrendered to the police, and is believed to have fingered Southern Police District Superintendent Johnny Orme as the gang’s ringleader. Orme, who remains at large, was also suspected of operating an illegal money-lending business to unlucky gamblers at Resorts World Manila and Solaire Resort & Casino.

On Tuesday, PNP director general Ronald dela Rosa announced plans to “post intelligence personnel at [Manila’s gaming zone] Entertainment City and monitor policemen who are always spending time there.”
