BJP state president V Muralidharan said that the missing of the CD, containing the call details of the solar scam, was mysterious.
In a statement issued here on Friday, he said that the incident questions the credibility of the investigation.
Muralidharan alleged that some higher ups were involved in the missing of the CD.
He pointed out that what had been lost was an important evidence meant to be kept in the safe custody of the Home Department.
No one from outside can steal it from the custody of the State Crime Records Bureau(SCRB).
The CD, containing the phone call details, could be stolen only with the help of top police officers.
He said Home Minister Thiruvanchoor Radhakrishnan should be held responsible to explain the loss of the CD as there had been allegations about moves to save some of the top persons in the Ministry.
He said that with the missing of the CD , evidence related to one of the most discussed cases in India was lost and there was a mystery behind this.
He also alleged mystery behind Thiruvanchoor’s revelation about the missing CD at this stage.
