The trial of Sayed Zabiuddin Ansari alias Abu Jundal, an LeT operative and a key plotter of the terror attacks, is currently underway.
Headley, arrested for being part of the conspiracy, was later made an 'approver' (prosecution witness) and his evidence was recorded from a US prison through video link in 2016.
"Hotel owner Paras Bumb deposed today. Headley had stayed at his hotel during his visit to Pune," special public prosecutor Ujjwal Nikam told PTI.
A native of Beed district in Maharashtra, Jundal was deported to India from Saudi Arabia in June 2012.
