Three senior officials of Dimapur, including the SP and the central jail chief, were suspended on Friday and a judicial inquiry was ordered into the lynching of a rape accused by a mob in this Nagaland town where the situation was stated to be tense but under control. One person identified as Inito Swu, who was among the five injured in police firing on the mob, succumbed, police said. Neighbouring Assam was put on high alert by the Centre following the incident in Dimapur as the rape accused Syed Farid Khan is believed to be from that state. Khan had allegedly raped a Naga woman several times before he was arrested on February 25. Infuriated by the alleged rape, the mob had forced its way into the Central jail on Thursday, pulled Khan out of the prison, paraded him naked before lynching him.
