A Bihar court acquitted Union minister Giriraj Singh and 22 other people in connection with a nine-year-old case that was lodged after they staged a rail blockade. Singh, along with LJP MP Veena Devi and BJP leaders Ram Surat Rai and Suresh Sharma, was among those who appeared before the MP/MLA court at Muzaffarpur on Saturday in connection with the Railway Act case lodged in 2014.
