Costa Rica arrests Chinese-Costa Rican at politician's event; PPSO denies ties

Guobin Tam Zhang, a Chinese-born naturalized Costa Rican, was arrested at Laura Fernández's victory celebration on a U.S. extradition request for alleged drug trafficking. The PPSO (likely a political party or security body) denies any connection to the extraditable individual. The incident raises questions about political associations and potential security lapses.
