Kabul, Aug 27 (DPA) One of the youngest Afghan detainees, who was released from the US prison in Guantanamo Bay in Cuba earlier this week, will sue the American government to compensate him for mistreatment for seven years in custody, his lawyer said Thursday.

'The mistake has already been made, and I don't think that the American government could really resolve that in his favour,' lawyer Eric Montalvo told a press conference.

'So the way forward right now is to avail the Afghanistan government and the US government of funding to help train him and get him back to normalcy,' he said.

'You cannot have this argument that we are scared that we are letting people go when they are going to harm, or we are scared that they are going to be problems, but yet you create the problems yourselves,' he said.

Mohammed Jawad, who is believed to be in his early 20s now, was released after nearly seven years in US custody. He was captured in Kabul in 2002 on charges of throwing a hand grenade at US military vehicle in downtown Kabul, wounding two US soldiers and their Afghan interpreter.
