VADODARA, Sept 5: The Gorwa police claimed to have solved a theft of Rs 3.45 lakhs with the arrest of a security guard from a private detective agency. The theft occured at room no 5 of the Bhailal Amin Hospital on July 28.The incident was particularly mysterious because access to the first floor was banned at night and all the gates to it were always locked.A security guard, Ashok Kumar Yadav, posted at the hospital, had been removed from service by the detective agency employing him after Yadav had a fight with the hospital's canteen contractor on July 27 night. Since the theft occurred soon after Yadav had been removed, and he also proceeded for his native place of Mainpuri in Uttar Pradesh soon after the theft, the finger of suspicion pointed towards him, the police said.Taking this line, a police party consisting of PSI A M Syed, head constables Ganpatlal and Mahendra Singh and constable Maljibhai went to his place and arrested him. During interrogation, Yadav admitted to having committed the theft.Yadav told the police that he had procured a screw driver after the fight with the canteen operator and climed on to the first floor building using a water pipeline. He removed the door handle holding the lock with the screw driver and broke the steel cupboard, from where he got Rs 3.45 lakhs in cash.
