Ranchi, Apr 16: Twenty GRP personnel were suspended for "security lapse" which led to an attack at Chandrapura government railway police post by MCC ultras in Jharkhand's Bokaro district on Monday, a senior official said here today. "The officer-in-charge, two of his sub-ordinates and 17 other policemen attached to the post have been suspended for laxity," inspector general of police (railway) I Lakra said today. Lakra, who conducted an enquiry into the incident, submitted his report to the police headquarters last night. Over 100 ultras had looted 23 rifles, two sten guns, 540 rounds of rifle bullets, 70 sten gun bullets, seven pairs of police uniform and a cash box. Bureau Report
