Activists of the Maharashtra Navnirman Sena stepped up their campaign against north on Monday. They ransacked the local income tax office, alleging that it had discriminated against local youths. Supporting the campaign, MNS Chief Raj Thackeray said Maharashtra's development would be impossible because of the influx of north Indians. The MNS activists were apparently angry over an interview for a lower-level post in which the maximum candidates were from Bihar.
