In summer 2003, the 24-year-old Khawaja began visiting
paintball and
pellet gun ranges with friends, signing in at the desk with
pseudonyms. One friend, Younes Lasfar, got Khawaja to store two rifles and some ammunition at his house, and Khawaja complies, storing them under his bed. In October, Khawaja flew to Pakistan, and is alleged to have met with Khyam who gave him a medical kit,
invisible ink set, cell phone
SIM cards and cash, which he allegedly brought to
Abu Munthir in Pakistan. On October 19, Khawaja sent an email to
Mohammed Junaid Babar, stating; "I will start on the remote devices thing right away and will let u know once we have it ready for testing and i find some of the things for testing.
Urea, nitro phosphate, anything else we need?". During this time, Khawaja also began corresponding with
Zeba Khan after reading her articles on the internet, and arranged to once again travel to Pakistan to meet her, going out to dinner with her and Babar. On October 29, Khan announced that she was
engaged to Khawaja, though later the couple decide to cancel the marriage but remain friends. Prosecutors allege that the following month, the British-based group and Khawaja began discussing potential explosives to be used in the service of "
jihad". ==Arrest, trial and sentencing==
