The three-- Nakai Shinsuke (45), Undos Yoko (49) and Watarida Macula (61)-- arrived here on Wednesday night by an Air Asia flight from Kuala Lumpur on way to Idinthakarai, focal point of the protests against the Indo-Russian project.
Airport officials, who received a tip-off from central Intelligence officials about their arrival and plans to visit the agitation site, took them into custody and after questioning deported the three within an hour of their arrival at 7 PM, the sources said.
In February, a German national --Sonnteg Reiner Hermann-- who was suspected to have been involved in the anti-nuclear protests, was deported as he was found to have indulged in activities not consistent with his tourist visa.
