A disabled man was injured in a huge explosion as he attempted to warn the shop owner in northern China.

CCTV footage filmed in the city of Yulin in Shaanxi Province on February 21 shows a man with mobility issues spotting the smoke coming out of a shop when he walked past.

He attempted to warn the shop owner but an explosion knocked him to the ground.

The man suffered a cerebral contusion and was hospitalised.

According to the shop owner, there was no one in the shop when the incident happened.

According to an anonymous insider, the explosion might have been caused by a burning scooter in the shop and the case is still being investigated.

2月21日，陕西榆林。监控中一门店内浓烟四起，黑烟从各个门缝隙在往外漏。此时一名腿脚不便的男子在街头行走，看到店内浓烟滚滚，马上改变路线加快脚步走上前欲提醒，他边大喊老板边用力拉开玻璃门，不料玻璃门被拉开的瞬间发生爆炸，男子直接飞出倒地，双腿颤抖久久无法动弹。后还陆续发生了数次爆炸，周围路人被吓到快步离开。
被炸男子目前已经住院，他对此回应称：头上受伤，话也不想说。
该男子的一位朋友介绍，男子被炸倒后，先是在家休息了一天，结果还是不好，还吐血，后来才送到医院，被诊断为脑挫伤，需要住院。
爆炸店铺的店主介绍，店里当时没人，等他赶到的时候，派出所消防车都来了，被炸伤的男子和他朋友也没打招呼就走了。他现在也不太清楚具体情况。
据一位匿名知情人透露称，疑似为门店内电瓶起火所致，具体还在调查中。
