Chandy issued the orders on the basis of a joint letter given to him by Malayala Manorama Managing Editor Philip Mathew, Mathrubhumi Managing Editor P V Chandran and Kerala Kaumudi Managing Director M S Ravi yesterday.
According to a CM's office release, the Chief Secretary E K Bharath Bhushan has been asked to probe the issue and subit a report within three days.
Following this, a section of the local press had reported that some reporters working in three leading Malayalam dailies had run stories supporting the neighbouring state receiving benefits from the official concerned.
In their joint letter, the editors wanted the government to probe how such defaming allegations against their dailies had crept into the intelligence report.
Chandy had a few days ago refuted the charge of leak of information and said intelligence reports should be taken only as an intimation to government to act with greater vigilance.
