Calling Biharis a "necessity" for the capital and not a "burden" on it, a proud chief minister of Bihar on Sunday said that if Biharis residing here did not work for a day, the city would come to a standstill. Nitish Kumar was addressing a crowd of over a few thousand people - largely Biharis settled in the city - at Bihar Shatabdi Utsav that celebrated 100 years of Bihar's statehood at Delhi's Coronation Park in Burari. The event was organized by the members of Bihar's legislative council.
