Chennai: The CB CID sleuths probing the 'disappearance' of environmental activist R.S. Mugilan, who involved himself actively in anti-Sterlite protests and other pro-people movements, has informed the Madras High Court on Thursday that they have got vital clues in the case.

A status report on the ongoing investigation was filed before the court by the probe team, even as Mugilan's kin and opposition parties questioned the credibility of the probe which confined itself to 'harassing' those close to Mugilan instead of carrying out a credible inquiry.

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.
