Jakarta. Indonesian Air Force personnel have detained seven men, including five Chinese nationals, who were claiming that they work on the Jakarta-Bandung high-speed railway, which is currently under construction.
Officials initially suspected that the men, who were arrested for trespassing at the Halim Perdanakusuma Airport in East Jakarta, may have been involved in espionage activities.
"We became suspicious when we saw the foreigners drilling in the military zone. We investigated and found that they did not carry any permits or documents from their embassy," Halim Air Force Base commander Col. Sri Mulyo Handoko told detik.com on Wednesday (27/04).
Sri added that when questioned, the workers claimed ignorance, but that it later turned out to be an administrative issue.
"We need them to carry their documentation and security clearances at all times while on site," the base commander said.
The five Chinese workers, who were wearing military-style uniforms, were unable to converse in either Indonesian or English.
The Jakarta-Bandung high-speed railway is currently under construction by Kereta Cepat Indonesia China, with the Halim Perdanakusuma Airport earmarked as the train's Jakarta terminal.
However, the Air Force has rejected the proposal amid concerns that the construction project may interfere with its operations at the airport, which serves both military and civilian purposes.
