Chennai: Petrol bombs were hurled at two post offices at Mandaveli and Mylapore by unidentified persons on Tuesday morning.
There was damage to the property, but no one was injured in the incidents.
The Tamil Nadu Police arrested four activists of Dravidar Viduthalai Kazhagam, a little known Tamil outfit, for throwing petrol bombs at two post offices. One of them is suspected to be a member of a political outfit, a newspaper said.
The activists want India to boycott the Commonwealth Heads of Government Meeting (CHOGM) to be held at Colombo next month.
Sources in the Fire and Rescue Services department said the fire had been doused.
Following the attack, police beefed up security at central government offices and installations across the state. The Sri Lankan mission office here has also been provided additional security.
