Members of Bru Students Association (BSA), Bru Cultural Organisation (BCA) and Aizawl Bru Welfare Committee (ABWC) went around the villages, some of which were rocked by violence following the murder of a youth at Bungthuam village, near Tripura border on November 13.
Superintendent of police, Mamit, LR Dingluaia said the delegation members also met top district officials.
"The team members informed their (Bru) people in the district that the state government has been making all out effort to contain the recent spurt of communal tension and there is no reason to flee to neighbouring Tripura," Dingluaia told PTI over phone.
Hundreds of huts had been torched as tension escalated following the murder of Zarzokima, an 18-year-old youth, by suspected Bru militants.
The chain of events caused serious setback to the proposed repatriation of Bru refugees from six relief camps in North Tripura where they had been lodged since 1997.
While the proposed repatriation of Brus from November 16, from Kanchanpur sub-division in Tripura, could not take off, around 400 Bru families crossed over to Tripura since November 13, officials said.
