New Delhi, Jul 3 A Delhi court on Friday extended till August 1 the judicial custody of six foreign nationals, including five Ukrainians and one US national, accused of breaching national security.
The foreign nationals were produced before NIA Special Judge Prashant Sharma after the completion of their judicial custody.
They are being probed for a wide-ranging terror conspiracy which involves suspected links to ethnic rebel groups in India and Myanmar, and imparting drone training to them.
US national Matthew Aaron Van Dyke was produced in the court on a wheelchair.
Another co-accused, a Ukrainian national, is likely to be produced before the court on Saturday.
Meanwhile, the court noted that the six foreign nationals had consented to provide their voice samples in response to the National Investigation Agency's (NIA's) plea seeking the same.
The court is likely to provide a date on Saturday to the premier agency for obtaining the samples.
Sources said Dyke is not having prison food and is subsisting on liquids, including juice and soya milk.
They said an application will be moved shortly on his behalf seeking outside food.
The accused persons were arrested on March 13. On March 16, the court allowed 11 days of custody to the federal agency for interrogation, which was then extended by another 10 days.
In the remand application on March 16, the investigation officer, citing the FIR, said that some Ukrainians had entered India on tourist visas on separate dates and had flown to Guwahati, from where they travelled to Mizoram without obtaining the requisite documents, such as the Restricted Area Permit or Protected Area Permit.
Thereafter, these individuals illegally entered Myanmar to impart pre-scheduled training for Ethnic Armed Organisations (EAOs) in that country, the application said.
The agency further said that the scope of the investigation is "very wide", covering not just the commission of acts but also the "advocacy, incitement and preparation" of terrorist activities.
The court had earlier observed that these allegations definitely involved national security and the country's interests, and broadly attract Section 18 (punishment for conspiracy) of the Unlawful Activities (Prevention) Act.
On April 6, the accused persons were sent to 30 days' judicial custody, which was later extended.
