Local people claim they saw the man targeting the statue; a passerby even took a picture with his mobile phone but the man has not yet been identified as the photo is from a distance and does not show his face.
Senior police sources have told NDTV that they do not suspect any political motive behind the attack on Gandhi's statue. Police suspect it is a "one off incident."
Police sources have described the man wearing a brown shirt and saffron coloured lungi, which is commonly worn in Kannur and other parts of Kerala.
An investigation has been launched into the incident.

Police across states have tightened vigil around iconic statues. In the national capital, as a precautionary measure, the Delhi Police has asked its officers in various police stations to stay alert.

Vandalising statues started on Monday when the statue of Lenin was bulldozed in Tripura after the BJP swept the assembly elections. Over the last three days, statues of Periyar and Syama Prasad Mookerjee were vandalised in Tamil Nadu and West Bengal.
The Centre has taken a strong stand and directed state governments to take strict action against anyone damaging statues.
