Intersol
From Tardis Wiki, the free Doctor Who reference
Intersol were a group of beings dedicated to locking up dangerous aliens. They went after Majenta Pryce, an old enemy of theirs. They looked for her all over the galaxy, including Thinktwice prison and Stormlight House. They finally found Majenta with her friend The Tenth Doctor on the Planet Earth.

They managed to chase the Doctor and Majenta from not being able to time travel in the Tardis. They then captured the Doctor, but Majenta got away. Majenta was later found by Zed an employee for them, who then went on to fire at her. (DWM: The Crimson Hand)
