(Missing cab driver Yogesh Raut)

When she was on her way home in Pune from the IT company where she worked, Nayana Pujari was raped and murdered, allegedly by four men.She was traveling in a car owned by her company. The driver and a security guard assigned to escort her home were arrested, along with two friends.Ms Pujari was 27 when she was killed in 2009. Her husband, Abhijit, asked for a fast-tracked trial for his wife's case, but his petition was rejected by the Maharashtra Home department.In September 2011, when he was brought to the Sassoon Hospital for a medical check-up, the cab driver, Yogesh Raut, escaped. He didn't have to try hard. He said he wanted to use the toilet. A policeman removed his handcuffs and he was allowed to wander away unsupervised.

The escape paralysed the case. Mr Raut has still not been caught. Police sources say that in narco-analysis tests conducted on him, he allegedly referred to having raped another girl.If you have seen Mr Raut (photo accompanies this article), please contact:
