The documents were found yesterday at Bandra police station, Mumbai Police Commissioner Rakesh Maria said today.
"We have initiated an inquiry as to how the papers went missing. Action will be taken against policemen because of whom the documents had gone missing for a few days," he said.
The documents contain important information relating to the case, the case diary and statements of witnesses, police said. Somebody might have shifted the documents from the record room during the renovation of the police station after which they were not traceable, sources said.
On August 21, Bandra police had informed the sessions court holding a fresh trial in the case that the documents related to witnesses' statements and the case diary had gone missing. The court had directed the police to locate the documents by September 12.
On September 28, 2002, the Salman Khan's car had run over a group of people sleeping on the pavement outside a Bandra bakery, killing one and injuring four.
