Pakistani authorities have turned down a US request to shift the suspected CIA contractor Raymond Davis from Lahore's Kot Lakhpat Jail to the Governor House for his safety. An unnamed official told 'The Express Tribune' newspaper that after examining the different aspects of the US demand, the Punjab government refused it and termed it unworkable. The US had reportedly proposed that Davis, currently being held in Kot Lakhpat Jail, be shifted to the Governor House, two rooms of which could be declared a sub-jail. The US also proposed that Davis' trial should be conducted in the Governor House. The demand was made to ensure safety and well-being of Davis as the American media has expressed concerns that his detention in jail posed a risk to his life. The Punjab government assured the US that the best possible security arrangements have been made for Davis, who was arrested in Lahore on January 27 after he shot and killed two armed men he claimed were trying to rob him. Police have rejected Davis' claim of acting in self-defence and have booked him for murder.
