Days after being granted default bail in the Myanmar training camp case, US national Matthew Aaron Van Dyke on Tuesday paid Rs 5.5 lakh in compounding charges to the FRRO (Foreigners Regional Registration Office) for offences under the Immigration and Foreigners Act.His legal team indicated to The Tribune that they plan to move a discharge plea before the special NIA court later this week.Van Dyke was granted default bail on September 18 after the NIA earlier this month filed a chargesheet against him and six Ukrainian nationals in the case, while dropping the UAPA offences against them.In its chargesheet filed before the special court on September 8, the NIA had invoked only Sections 21 and 23 of the Immigration and Foreigners Act, 2025, against the seven accused, while dropping provisions of the UAPA.The two offences cited in the chargesheet are compoundable at the level of the FRRO.While granting default bail to Van Dyke on September 18, Special NIA Judge Prashant Sharma directed him to remain in Delhi and made it mandatory for him to join the investigation whenever called by the investigating officer.The court had also noted that the same reasoning applied to Van Dyke’s six Ukrainian co-accused, who remain in judicial custody. It further directed that copies of the ruling be sent to them through jail authorities so that they could pursue their own default bail applications.Van Dyke’s lawyer Rohit Dandriyal had told The Tribune last week that the bail was granted to his client as the NIA could not prove the charges levelled against him under the UAPA even after 180 days of incarceration. “This is the reason we had applied for bail and it was granted by default,” he had said.Van Dyke, along with the six Ukrainians, was arrested in March this year for allegedly imparting drone warfare training, illegal border crossings and links to armed groups operating near India’s North-East region.According to the central agency, the accused entered India on tourist visas and travelled to the North-East without obtaining the mandatory permits. It was alleged that they subsequently crossed illegally from Mizoram into Myanmar, where they were involved in training ethnic armed organisations.The NIA had informed the court that though the UAPA provisions had not been included in the chargesheet, the investigation under the anti-terror law remained open.The agency had originally arrested the accused in a terror conspiracy case over alleged links with ethnic armed groups operating in India.Van Dyke’s family had sought urgent diplomatic intervention from the US, alleging that he had been denied basic detainee rights in Tihar Jail, where he is currently lodged.Sons of Liberty International, the NGO founded by Van Dyke, said in a statement issued on August 30 that US Ambassador to India Sergio Gor had “previously briefed Foreign Secretary Vikram Misri and Secretary of State Marco Rubio on Matthew’s situation during his (Rubio’s) visit to Delhi on May 24-26”.When asked last week about the NIA’s decision to drop UAPA charges in its chargesheet, Ministry of External Affairs spokesperson Randhir Jaiswal said the matter was sub judice.
