Tabatabainejad allegedly refused to show his school ID to a fellow student acting as security at the college library Instructional Computing Commons (CLICC) lab at Powell Library during finals week. A UCLA ID card with magnetic strip is needed to enter into the Library after hours and therefore it was assumed that all individuals in the library were students and had valid ID cards to gain access. Asking students to show ID was not a common practice and for this reason the student refused to show his ID and instead asked the community officer if he had asked anyone else that evening to show their ID.
