A Mumbai court has today acquitted four men accused of kidnapping and murdering Mumbai teenager Adnan Patrawala in 2007, who they had allegedly met via social networking site Orkut. The verdict is being read by the city as a moment of shame for the Mumbai Police, whose lethargic inquiry has belied what experts say was an open-and-shut case. The court said there was not enough evidence to prove that the arrested men are guilty. A fifth - who is a minor and is being tried separately - is also likely to be declared innocent.
