Just as PM Modi was to arrive, men with black flags climbed on top of hoardings and released black flags and balloons outside Chennai Airport.

On any normal day a visit of the Prime Minister would be celebrated with saffron flags hoisted all across the city, but this time Chennai was different and sported black as its predominant colour.

Hundreds of protestors wearing black with black flags and black balloons have been raising anti-Modi slogans and have been demanding the formation of the Cauvery Management Board.

Just as PM Modi was to arrive, men with black flags climbed on top of hoardings and released black flags and balloons outside Chennai Airport.

Six kilometres from the airport, another mixed group led by Pazha Nedumaran, president of Ulaga Thamizhar peramaippu, TVK party's T Velmurugan and few pro Tamil factions staged their protest.

Banners carried by the protesters read 'Go Back Modi, Down Down Modi'. The banners also made a mention of Tamil Nadu's right over Cauvery.

Pazha Nedumaran said, "We want the Centre to hear our demands. It is only electoral politics that the Centre is doing now. There is no state government in Tamil Nadu. It is only a dummy government working on the instructions of the Central government."

Wearing a black shirt, actor Kamal Haasan in a video message on social media to Prime Minister Narendra Modi said, "People of Tamil Nadu are fighting for justice. Justice has been given but it is not being executed. People have started to believe that this delay is due to Karnataka elections, which is dangerous and embarrassing. I hope you will change this."

"You have to constitute Cauvery Water Management Board for the betterment of Tamil and Kannadiga people. That's your duty. To remind you is my duty. Whatever I haven't said through this video, I shall include in a letter that I'm writing to you. Please act and pave way for change." Haasan added.

In Erode, a man tried to immolate himself to protest Modi's arrival in Chennai. Dharmalingam also wrote on the wall of his house that he condemned Modi's visit. He has been rushed to Erode government hospital.

"As PM flew to the Defence Expo from the Chennai Airport, he might have missed the protest on the roads but he might have got a glimpse of those black balloons in the air," A protester said.

After his protest against Prime Minister Narendra Modi, Marumalarchi Dravida Munnetra Kazhagam (MDMK) chief Vaiko has accused the Chief Justice of india (CJI) of dancing to the tunes of the Modi government.

He said that Cauvery basin will become a desert in the future and turn into an Ethiopia. "I'm accusing CJ of dancing to the tunes of the Centre. He did not allow TN advocate to raise Tribunal issue," said Vaiko.

Vaiko in his fierce protest had raised anti-Modi slogans and called PM Modi a coward. "Modi is Coward. Only thieves will jump wall. Why didn't he come by road like Nehru. He has broken a wall between IIT and Cancer institute only thieves jump walls (sic)."

"Its a treacherous betrayal by the central government," Vaiko said adding that PM Modi has no right to set foot inside the state of Tamil Nadu after cheating them off their right to the Cauvery Management Board.

Vaiko had raised black flags and also released black balloons into the air as a protest against the PM.
