Security at the Raj Bhavan in Thiruvananthapuram has been stepped up after a caller from a Gulf country issued a threat to the life of Kerala Governor R S Gavai, police said today.
The call to Raj Bhavan last night came hours after Gavai had given sanction for the CBI to prosecute ruling CPI-M state Secretary Pinarayi Vijayan in the SNC Lavalin corruption case, overruling the LDF cabinet recommendation against it.
The caller spoke in Malayalam, police said.
A complaint was lodged with the Museum police station.
Using details in the caller ID which recorded a 11-digit phone number, police said it found the call was made from a Gulf country.
