An alleged Chinese spy mayor and sacked mayor Alice Guo arrived in the Philippines Senate building to continue probe.

Footage shows the dismissed official being escorted by police as she climbed down a bus in Manila on September 17.

Reporters flocked around her, eager to ask questions. She was wearing a helmet, face mask, sunglasses, and a bulletproof vest while security pushed the crowd away to let them pass.

Alice Guo, also known as Chinese national Guo Hua Ping, was detained by Indonesian police in Tangerang City along the western border of Jakarta in the early hours of September 4. She was the subject of multiple money laundering charges filed by Philippine law enforcement agencies.

Her controversial case stemmed from a raid that uncovered a sprawling Chinese online casino built on land she partly owned in Bamban town.

Guo was last seen in public on May 22. She was dismissed by an anti-graft body and soon went into hiding, refusing to appear before the Senate because 'she was traumatised'.

The mayor sparked fury among locals as she was later revealed to have slipped past border checks, travelling through Malaysia, Singapore, and finally Indonesia, where she was caught.

Indonesian police were on alert following the arrest of Guo's foster sister Shiela and their family friend Cassandra Ong, who both accompanied her while fleeing, in Batam on August 20.

Guo, a newcomer in politics, had insisted on her Filipino heritage in interviews with local media. However, fingerprint matches allegedly found that she was Chinese citizen Guo Hua Ping, sparking outrage and calls for her ouster.

The controversy comes amid the Philippines' territorial conflicts with China over parts of the South China Sea.

Expansionist China currently lays claim over almost the entire South China Sea, one of the world's busiest sea lanes. But a United Nations-backed tribunal in 2016 deemed its claims groundless.

The Communist rogue state - accused of genocide for its crimes against the Uyghur population - has been steadily increasing its influence in recent years through investment in developing countries.
