The Sri Lankan Minister for Livestock and Rural Community Development, Arumugam Thondaiman, was forced to abandon his visit to the Tamil Nadu city of Coimbatore after protestors besieged his residence.
Arumugam Thondaman's visit drew angry crowds to his hotel on Saturday, before he fled to Chennai.
The protestors, mostly supporters of Naam Tamilar Katchi (NTK), demanded Thondaiman leave India immediately and attempted to jump over the gate of the hotel.
15 people were arrested by police over the protest.
Thondaman is a member of the Ceylon Workers' Congress, a coaliton partner of the ruling SLFP and President Mahinda Rajapakse.
This is the second such incident in Tamil Nadu in a month.
In January, suspected members of the MDMK and NTK stormed into the house of a priest and threw rocks and slippers at a relative of Mahinda Rajapakse, who was about to perform a religious ritual.
