It was a stunning twist in the Pradyuman Thakur murder case. The 11 year old boy was found murdered with his throat slit on September 8 in the toilet of the Ryan International School in Gurgaon. The CBI has now detained a senior student of the school who is suspected of murdering the 11 year old boy. It may be recalled that the local police had arrested a conductor and even extracted a confession out of him. It was further reported that the boy had been sexually assaulted.
