accused in a bizarre plotnisky. Authorities say he tried to kill his roommate over a period of months by slowly poisoning him. A former Lehigh university student is behind bars accused of trying to for several months kill his roommate, juwan royal. He experienced extreme pain in his lower extremities and burning and numbness. Reporter: 22-year-old yukai yang an international student from China now faces several charges including attempted homicide and aggravated assault. Authorities say the chemistry major carried out Ang attempted murder plot inside his dorm slowly and discreetly starting in February. The district attorney saying the victim wrote in a statement he remembered drinking water in a bottle and immediately felt a burning sensation on his tongue. According to authorities yang put thallium, a tasteless, odorless poisonous metal once widely used in rat poison in his roommate's milk and mouth wash. Royal reported symptoms of dizziness, shaking and vomiting. This was over a period of time where a small amount of this poisoning was occurring. When somebody commits what I would call clearly a premeditated murder, in their mind they think the only way to resolve this problem is to kill the person and you have to think about it almost every day, which I think adds sort of a level of evilness to it. Reporter: In April, yang was arrested and released on bail for damaging royal's television, bed and desk writing a racist slur along with "Get out of here" in black marker. And investigators saying yang admitted to buying the poisonous chemical online but says he planned to use it on himself if he didn't perform well on exams. As for that former roommate, royal is still recovering still coping with side effect. Amazing he thought they were friends this whole time. They lived together for a very while. Very scary. Awful. Scary, indeed. Thank you for that, Eva.
