Chennai: The CB-CID has been entrusted with the investigation and tracing of a Tamil Nadu environmental activist Mugilan alias Shanmugham. Mugilan went missing on February 15
shortly after he claimed involvement of senior police officers in the police firing at anti-Sterlite
protesters at Tuticorin on May 22 and 23 last year which claimed the lives of 13 people.
The state government has ordered CB-CID probe following repeated pleas by activists and political
parties to trace the missing activist.
