At the beginning of Day 6, Yusuf was arrested at his home by the FBI on suspicion of terrorism. Jillian and her family watched from their window as Yusaf was removed from his home and two neighbors began to harass Yusuf's son, Ahmed. Ray prevented the neighbors from hurting Ahmed, and asked Ahmed to stay at his family's home until the neighbors calmed down.
Later that morning, Ahmed returned to his home to retrieve a package. While in his home, he was attacked by Stan Miller, one of the neighbors who harassed him earlier that day. Ahmed shot and killed Stan, but not before being severely wounded by a piece of sharp glass.
Ahmed then took Jillian, Scott, and Ray hostage. He demanded that Jillian, a nurse, bandage Ahmed's wound. Jillian told Ahmed that the wound was too deep, and that she should go to the hospital. Ahmed then demanded that Ray deliver payment for a trigger for a suitcase nuke since Ahmed could no longer do so himself. After the paymet was exchanged for the trigger, Ahmed then told Ray to deliver the trigger to terrorist leader Abu Fayed in Valencia. In return, Ahmed released Jillian.
While Scott was still being held by Ahmed, Jillian began to drive away from her home in her minivan. Although Ahmed warned her not to so, Jillian called the police and informed them of the hostage situation in her home. CTU arrived at her home and were successful in freeing Scott, although Ahmed was killed in the process. CTU was then able to use information from Scott to track the suitcase nuke to Fayed's warehouse in Valencia, but the device was detonated before it could be confiscated.
