Trains were set afire, window panes of buses smashed and passersby, including a ruling BJP MLA, pelted with stones on Thursday in Bihar by Army job aspirants whose protest against the Centre's short-term recruitment scheme, 'Agnipath', continued for the second consecutive day. Police fired teargas shells and charged baton to disperse the angry youngsters who blocked railway tracks, threw burning tyres on roads and performed push-ups and other drills on the streets as a mark of protest against the new recruitment process, under which hiring has been proposed for a four-year-period followed by compulsory retirement, for at least 75 per cent of the personnel, without any pension benefits.
