Government Tip Off Prompted Spy Agency to Look into Federal Scientist, CSIS Says The latest developments in the Dennis Lu case reveal that Natural Resources Canada initially approached the Canadian Security and Intelligence Service (CSIS) with concerns about Lu's activities over two decades ago.

A closer examination of the timeline shows that CSIS had been briefed on Lu multiple times, yet nothing seemed to be done for 23 months after the last briefing.
