Uttar Pradesh Chief Minister Mayawati on Saturday said she was ready to recommend a CBI inquiry into the lynching of PWD engineer allegedly by a BSP MLA provided the probe agency takes over the cases referred to it by the state government including those relating to police recruitment during Samajwadi Party rule."The government has no objection to referring the engineer (M K Gupta) murder case to CBI but only when the investigating agency accepts all the dozen-odd cases referred to it, including the recruitment scam of police constables under the previous Mulayam Singh Yadav government, which has been turned down," she said.Assuring detailed investigation as well as stern action against all those found involved in the murder of the engineer, Mayawati said if required the government would also order narco analysis test of BSP MLA Shekhar Tewari arrested in connection with the incident as well as the station officer of Dibiyapur police station, where the crime took place, Hoshiyar Singh who has since been suspended.Mayawati said she has come to know that the MLA was a habitual drunkard and it was being ascertained whether someone might have taken advantage of this weakness She said Hoshiyar Singh had been posted in the same police station during the SP rule and had close links with Samajwadi Party leaders and it was being ascertained whether there was any political conspiracy behind the incident.
