A Ph.D. student at the University of New Hampshire is facing criminal charges after an apparent hazmat situation near campus over the weekend. Police said 29-year-old Emad Mustafa called authorities himself on Saturday, saying he may have been exposed to a toxic chemical. He was taken to the hospital and treated, but that process launched a multi-department investigation. Police said a search warrant was issued at the direction of the Strafford County Attorney’s Office and Mustafa was arrested. Mustafa is now facing charges for alleged reckless conduct with a deadly weapon and improper disposal of hazardous materials. Authorities have not said what kind of deadly weapon was allegedly found.
