Eight police officers accused in the Sohrabuddin Sheikh fake encounter case have objected to former deputy superintendent of police N K Amin's appeal for turning approver.
Officers who have objected include former deputy inspector general of police D G Vanzara, who is the prime accused in the case, as well as former superintendents of police Rajkumar Pandian and M N Dinesh.
Amin was said to have been close to Vanzara.
The police officers are accused of killing Sheikh in a staged gun battle in November 2005 and alleging that he was a terrorist planning to kill Chief Minister Narendra Modi.
Later, they allegedly killed Sheikh's wife Kausar Bi as well.
Amin had sought pardon from the court on Monday, requesting that he be allowed to turn approver.
On Tuesday, the court put off the hearing on his plea to August 3, following the objections raised by the co-accused.
The court also rejected Amin's request that he be transferred from the Sabarmati jail, where he is lodged with the other accused. Amin had said he feared for his life there.
But the court instructed jail authorities to keep Amin in a separate cell.
As approver, Amin can give vital information to the CBI about the sequence of events that led to Sheikh's killing by the Gujarat Police.
The officers allegedly shifted Sheikh and his wife from one farmhouse to another on the night of November 25, 2005. He was killed in a staged encounter the next day.
Kausar Bi was allegedly kept at the second farmhouse for a few days before being murdered. Her body was allegedly burnt and the ashes were thrown into the Narmada river near Bharuch district, around 200 km from Ahmedabad.
Amin's evidence can also make a watertight case against Shah, said to be a protégé of Modi.
