Karwar: Investigation was on into the case of mixing of tritium in a drinking water cooler in the Kaiga nuclear plant, Uttar Kannada Superintendent of Police Raman Gupta told reporters here.

Officials of the Nuclear Power Corporation of India Limited (NPCIL) were cooperating with the police and other investigating agencies. The case was too technical and this was the main hurdle in the investigation.

Mr. Gupta denied that there was any link between the case and the death of scientist Mahalingam and NPCIL employee Ravi Mule few months ago.
