Despite Manipur government's ban on his visit, a defiant NSCN-IM leader T Muivah today arrived at the state's frontiers from where he is set to embark on a journey to his birthplace. Prohibitory orders have been clamped and security heightened to avoid any unrest in the area. <br/>75-year-old Muivah reached Viswema village near the Nagaland-Manipur border on his way to his home village of<br/>Somdal in Ukhrul district in Manipur. Muivah would stay overnight at Viswema near the Mao gate on the inter-state border from where he would go to Somdal tomorrow, said Naga Hoho leaders, who are coordinating his entourage. In a hurriedly convened press briefing at the NSCN-IM headquarters last night, Muivah claimed he would go ahead with his planned visit to his village which was agreed upon by the Centre. The leader said, he failed to understand why Manipur is objecting to his visit, adding such move is not necessary as the visit is for peace, to meet family and friends and not to disturb anyone. The Manipur government has stepped up security measures and clamped prohibitory orders on the other side of the Mao inter-state gate to thwart the entry of the Naga leader into the state fearing breach of communal harmony.<br/>
