Imphal, June 24 -- A member of Meitei group Arambai Tenggol has been arrested for his alleged involvement in the murder of a 29-year-old man, which sparked fresh tensions in the ethnic violence-hit Manipur this month. Police said Longjam Khaba alias Boi, 35, is the main accused in the murder of Chesam Abdul Kadir, who had a 65% disability. Kadir's body was found on last Tuesday, days after Arambai Tenggol members allegedly abducted him. Police fired tear gas shells to disperse the protesters demanding action against Kadir's killers. Nine people, including six Arambai Tenggol members, were earlier arrested in the case. Police said the arrested accused admitted that Kadir died while they "questioned him" over an alleged theft attempt and buried his body near a riverbank. The murder came to light amid a series of arrests of Arambai Tenggol members as part of an ongoing crackdown in Manipur. On June 12 and 13, two Arambai Tenggol members were arrested for alleged involvement in a June 9 mob attack that injured a police officer. The arrest of five Arambai Tenggol members, including Kanan Singh, this month over their involvement in the ethnic violence in the state, triggered the latest wave of unrest in Manipur. The Arambai Tenggol demanded the immediate release of the five and announced a 10-day shutdown, which was called off four days later. Kanan Singh was dismissed from the police force this year over his alleged involvement in smuggling weapons and looting armouries. The authorities suspended broadband and mobile data services in Imphal East and West, Kakching, Thoubal, and Bishnupur, saying some "anti-social elements might use social media" to incite the public over Singh's arrest....
