Stone pelting occurred on the 12566 Bihar Sampark Kranti Express, traveling from New Delhi to Darbhanga, between Domingarh and Gorakhpur late Monday night. A 20-year-old passenger, Angad Gupta from Deoria, sustained a severe eye injury, with his retina rupturing. Angad was traveling from Badshah Nagar to Gorakhpur with his friend Raj Thakur.

The incident took place around 02:15 AM when Angad was talking on his mobile phone near the general coach's door. A stone struck him directly in the eye, causing bleeding and intense pain, leading him to collapse. Upon the train's arrival in Gorakhpur, the Railway Protection Force provided him with first aid. Later, doctors at AIIMS confirmed that his retina had ruptured and blood had accumulated, requiring a lengthy recovery. Despite treatment, Angad's eye remained closed. After receiving medical attention, he returned to his village, Babhnauli Pandey, Lar (Deoria).

Stone-pelting incidents on trains are increasingly frequent on the Gorakhpur-Gonda route, particularly between Gorakhpur and Domingarh. Just two days prior, the Gorakhdham Express was targeted between Munderwa-Orwara stations, resulting in cracked AC coach windows. In April, another Gorakhdham Express incident between Gorakhnath Bridge and Domingarh station left one passenger with a head injury and a female passenger hurt. On April 14, the Vande Bharat Express was also pelted with stones between Orwara and Basti stations. In May, the Humsafar Express was targeted between Uska Bazar and Siddharthnagar, injuring a female passenger, Shivkali, on her head. These recurring incidents raise serious concerns about passenger safety.
