Chandy was taken to a Kannur hospital for a check-up late Sunday night. Emerging from the hospital with his forehead bandaged, he said: "I am leaving for Kozhikode and from there will fly to Thiruvananthapuram."
The Communist Party of India-Marxist (CPI-M) has denied its involvement in the attack. A probe has been ordered into the incident and two CPI-M activists detained, while state-wide condemnation has poured in.
The incident occurred when Chandy was on his way to attend the annual Kerala Police athletics meet in Kannur.
