"The security in the jail was under central security forces who failed to stop the lynching. It is the Centre which is responsible for ensuring security of the inmates," Gogoi said outside the state assembly where Opposition members demanded steps for ensuring safety of Assamese people.
Meanwhile the body of Syed Farid Khan, who was beaten to death by the mob on March 5, was brought to his native Bosla village in Badarpur of Assam's Karimganj district.
The deceased's brother also denied reports that they are Bangladeshi nationals saying his late father was in the army and his two other brothers are jawans in the force.
A high alert has been sounded throughout Assam to prevent any untoward incident and to ensure the safety and security of Naga people in Assam in the aftermath of the incident.
The Nagaland government has kept paramilitary forces on standby to instill a sense of security among non-Naga communities of the state but there was no flag march.
Singh also assured all central help to Nagaland.
Gogoi had written to Singh and Zeliang seeking security measures to people of his state.
In his letter to Singh, he wrote, "Attacks on people of a particular community, especially to those belonging to minority, can have widespread repercussion in Assam, which has a huge population of Muslims."
Yesterday the Nagaland Cabinet suspended Deputy Commissioner Wezope Kenye, SP Meren Jamir and B. Chuba Phom, Senior Superintendent of Central Jail, for "their failure to control the situation".
Khan had been arrested on suspicion of raping a woman in Dimapur on February 24 and remanded in judicial custody in the Dimapur Central Jail the following day.
On March 5, the mob broke into the jail, dragged him out, stripped him naked, beat him up, pelted him with stones and dragged him towards the centre of Dimapur town, seven km away.
The girl, meanwhile, claimed before a TV channel that the accused gave her money to remain silent about the incident.
