Unidentified EV-series interrogation droid

This A4 laboratory assistant droid, a modified EV-series supervisor, was inside the Confederacy of Independent Systems' prison, the Citadel, in the dungeon along with a few BX-series droid commandos where Jedi Master Even Piell was being held in around 21 BBY. She was interrogating the Jedi about intel he knew. When the Lannik refused to talk, the droid was moving to remove Piell's good eye using its needle, but a team of Jedi and clone troopers that were sent to rescue the Jedi Master, burst in. During the rescue, the droid watched as its fellow droids shot by the clone troopers. Captain "Rex" blasted the droid through the head and with a final scream of pain, it toppled to the ground, and its red photoreceptors went out.
