The police are sending notices to the companies involved in the transportation of the container, the customs department and the Container Corporation of India Ltd (CONCOR), the custodian of the depot.
"We have asked them to submit a list of the agreements and documents pertaining to the transportation of the container and its content," he said.
Yesterday, police had said it is suspected that the leakage might have happened due to the containers not being properly sealed after being checked.
