Jahleed
From Mass Effect Wiki
Jahleed is a volus found down in the C-Sec Academy, trying to get one of the officers to take his case. He claims his work partner, a salarian scientist called Chorban, is trying to kill him and asks Commander Shepard to confront Chorban on his behalf. This begins the assignment Citadel: Jahleed's Fears.
In fact, Jahleed has an ulterior motive. He and Chorban were colleagues who stole a medical scanner from their workplace, and began using it to scan the keepers. Jahleed was supposed to analyse the data and disseminate their findings, but instead he decided to keep the data for himself. Chorban began following Jahleed to get the data back, so Jahleed hoped to get someone to 'take care' of his colleague.
When Shepard finds out the truth, the commander has a choice of how to deal with Jahleed. The commander can scan the keepers at Jahleed's request, letting him continue his clandestine research, or tell Jahleed to do the research legally.
If Shepard wants to punish Jahleed, the commander can order the volus to quit his research and walk away. Alternatively, Shepard can call the C-Sec officer over and say Jahleed has admitted stealing from his workplace. Jahleed protests, but the C-Sec officer tells him to save it for his lawyer.
[edit] Trivia
The C-Sec officer handling Jahleed's case is the same officer seen earlier in the game, telling Wrex to stay away from Fist.
