The accused, a resident of Jaisalmer, was nabbed yesterday and was taken to Jodhpur for initial questioning, the ADG (Intelligence), U R Sahoo, told PTI.
There were certain inputs that he allegedly had some "connections" with Pakistan's spy agency ISI.
He was on the radar of the intelligence agencies for some time now and was nabbed from his village.
"The man has not been arrested so far," the officer added.
