Congress president Sonia Gandhi today sought Prime Minister A.B. Vajpayee’s intervention in connection with two incidents in Gujarat. One is the murder of a pregnant woman and her unborn child. The other is the rape and murder of five little girls.In a letter to Vajpayee, Sonia said that she received a petition from Jannatbai Kallubhai Sheikh of Naroda Patia in Gujarat, who was an eyewitness to both crimes. Jannatbai has identified the perpetrators to the police but no action has been taken so far, she wrote.‘‘I thought it fit to bring this matter to your notice with the hope that you will agree that this particular case deserves your personal intervention,’’ Sonia said in the letter.The Congress president has asked the Prime Minister to ensure that an FIR is immediately filed in the case, the accused arrested and punished in the severest possible manner and the case handed over to the CBI for investigation.The petition, submitted to Sonia by Jannatbai during the former’s visit to Ahmedabad on May 1, has been enclosed with the letter. After giving details of the two incidents and naming some of the guilty, the petition says: ‘‘All this matter I have exposed before the police who came to the Shah-e-Alam camp to register the cases. I do not know what action has been taken by the police since then.’’
