Karnataka Home Minister G Parameshwara on Thursday said the Criminal Investigation Department (CID), probing the Protection of Children from Sexual Offences Act (POCSO) case against former Chief Minister B S Yediyurappa, has issued notice asking him to appear before it for questioning, and he may be arrested if necessary. "Notice has been served procedurally, the charge-sheet has to be filed by June 15. Before that they (CID) will file the charge-sheet. They will have to follow procedure for it. They will have to record his statement and produce him (in court), all these are procedures and the department will do it," he told reporters here. In response to a question, Parameshwara said: "If necessary they will arrest. I can't say (if) it is necessary, CID has to say it. If they feel it is necessary, they will do it." The BJP veteran, who is also a member of the party's parliamentary board, is presently in Delhi, and he is likely to join the probe after he returns, sources close to hi
