The Sri Lankan diplomatic mission in Chennai was placed under heavy security cover on Friday after a mob gathered outside to protest the killing of Tamils in the war-hit island nation.
Around 38 students were arrested Friday for holding protests outside the mission.
Sri Lanka Deputy High Commissioner P. Amza said the situation was under control.
"The director general of police (K.P. Jain) has assured us of our safety. The protesters today (Friday) were stopped some 100 metres from our mission and there is absolutely no cause for alarm," Amza told IANS.
Deputy Commissioner of Police A.G. Mourya, who is heading a 100-strong police contingent for security around the mission, said they were taking no chances.
"Our men held protesters at bay over 150 metres from the diplomatic mission. However, we are not taking chances after yesterday's (Thursday) stray incidents of stoning at a Lankan establishment," Mourya told IANS.
Meanwhile, several incidents of hunger strikes by students and lawyers were reported from all over Tamil Nadu to protest the sufferings of Tamils in Sri Lanka.
