BANGALORE, June 16: Two Bangalore City Corporation buses used by the staff of the Bangalore Metropolitan Task Force (BMTF) were stoned by petty shop owners and the public, as they went about clearing encroachments on footpaths on Residency Road, today. Though the BCC lorries were on a demolition drive to clear the encroachments, according to the shop owners, the BMTF staff behaved like hooligans and were very rough with the shop keepers.
