Imphal, May 07 2010: Around 300 Naga students and activists pelted stones at Manipur Bhavan in the national capital Friday evening and tried to storm it to protest the Manipur government's refusal to allow Naga separatist leader T.Muivah to visit the state.

'Around 300 of them arrived in buses.

They were carrying stones and attempted to storm Manipur Bhavan.

Some vehicles and windowpanes have been damaged in the stone pelting.

But no one has been injured,' Shambhu Singh, Manipur government's Resident Commissioner here, told IANS.

The situation was brought under control after additional forces were rushed to the site, Singh said.

The students also raised slogans against Manipur Chief Minister O.Ibobi Singh for not allowing Muivah to visit his ancestral village of Somdal in Ukhrul district in northern Manipur.

According to the police, traffic near the Bhavan, situated on Sardar Patel Marg near the Taj Palace hotel, was disrupted for more than an hour.

Over 300 policemen surrounded the area to prevent further trouble.

'There was heavy brick-batting, but no one was injured.

No one has been arrested or detained.

We are investigating the matter,' Shankar Das, deputy commissioner of police (New Delhi), told IANS.

According to a traffic police official: 'The protest led to a major traffic jam in the area' .

Rajni Singh, an HR professional, said she was stuck in the jam for more than an hour.

'The traffic jam spilled to the entire Chanakyapuri area, causing immense problems,' she said.

Marketing executive Mohan Rathore said he had some urgent work in Connaught Place but was stuck in the traffic for over two hours.

In Manipur's Senapati district, Nagas blocked the highway by resorting to sit-in protests leading to disruption in road communication between Manipur and the rest of the country.

Meanwhile, protesting against the Manipur government's move not to allow NSCN-IM leader T Muivah to visit the state, around 70 Naga students today tried to gherao the Manipur Bhawan here this evening.

The students, who came in three buses, also resorted to sloganeering, decrying the Manipur government's refusal to allow Muivah to visit his ancestral village in Ukhrul district.

"Around 60-70 Naga students came to stage the protest.

We have called in police to control the situation," Manipur government's Resident Commissioner in Delhi Shambhu Singh told PTI.

During their protest, the Naga students demanded that Manipur Chief Minister O Ibobi Singh should be arrested along with Manipur Police commandos, who were posted along the Manipur-Nagaland border.

The Manipur government had declared that Muivah would not be allowed to visit Manipur but the NSCN-IM leader vowed to go ahead with his tour.
