After Velez left the bus, he allegedly fought back as officers tried to handcuff him. A police officer used pepper spray to finally get him to stop resisting arrest.
Investigators said the backpack contained a student's computer, keys, and credit cards - valued at $2,500.
Velez is charged with felony larceny, resisting arrest, and trespassing. Bond was set at $2,500.
At a court hearing Tuesday, a judge ordered him to stay away from the Duke campus.
Velez has past charges dating back to 2010 that include unauthorized use of vehicle, breaking and entering, and trespassing.
