Is Bondsman part of his name?
Talk about it here.
Bondsman Tango-Veldt was looking for the Persuasion machine. He cloaked the ship which he thought managed to fool the Seventh Doctor into thinking they weren't there. He was told by his superior Acquisitor Prime to use any means necessary to collect Kurt Schalk. The Khlecht empire took over the ship and stopped them. (AUDIO: Persuasion)
