This is the chilling moment a jilted boyfriend fatally shot his ex-girlfriend outside her university dorm. 

Killer Pukkapong Chittarom, 24, went looking for student Natchareeya Thaprajit, 21, near her hostel in Bangkok, Thailand, on Monday. 

The pair had known each other for about five years but had recently separated, with Natchareeya refusing to reconcile with him.

He was seen on CCTV waiting outside her dormitory. She emerged with a classmate at around 11.30am local time. 

Natchareeya, a third-year business logistics student, was on her way to classes at the Suan Sunandha Rajabhat University and briefly stopped when she saw her ex.

Afterward, Pukkapong then sits down next to her, hugs her body, before turning the gun on himself, unloading a bullet into his mouth. He, however, survived the shooting.

Police and emergency services arrived but Natchareeya was pronounced dead at the scene. Pukkapong was taken to hospital after the bullet exited through his cheek.

Lieutenant Colonel Kittipon Udomsiripatchara said: "Police will investigate the case and speak with the family of the deceased.
