The banker, a Customs Department official and a magistrate recorded their statements before the Anti-Terrorism Court (ATC) Islamabad which is currently holding the in-camera hearing at the high-security Adiala Jail Rawalpindi.
"The banker testified in the court about the transaction involving huge money made from the account of Shahid Jamil. He presented documentary proof in this regard in the court," a court source told PTI after the hearing.
Earlier, the prosecution had established that Jamil used the money for terror activity.
The Customs official of the port city of Karachi submitted evidence to the court about the boats the alleged terrorists used to reach Mumbai, the source said, adding that the magistrate told the court about recording the statement of a witness who testified against one of the accused.
The court adjourned the hearing till November 4.
Mumbai attack mastermind Lakhvi and LeT operations commander Zaki-ur Rehman Lakhvi, Abdul Wajid, Mazhar Iqbal, Sadiq, Shahid Jamil, Jamil Ahmed and Younas Anjum were arrested in 2009 for their alleged role in the attacks that left 166 people dead and over 300 injured.
Lakhvi, 55, secured bail last December and was subsequently released from the Adiala Jail on April 10 after the Lahore High Court set aside the government's order to detain him under a public security act. He is currently out on bail and living at an undisclosed location.
