1escaParents are being warned to take extra care on escalators after a grandmother accidentally dropped her baby grandson 30ft to his death.

The tragic accident happened yesterday as the woman was out shopping with her grandson, who was just four months old. The woman was on the third floor of the Wu Yue plaza department store in Shanghai, China. She stepped onto the escalator to the second floor with the boy in her arms.

But as the stairs start to move beneath her, the woman stumbled into a gap, falling forward and leaning over the side of the handrail. Despite desperately trying to hold onto the little boy, he slipped from her grasp and tumbled to the ground below.

The boy’s mother and grandmother ran to his aid and the little boy was rushed to hospital, but died in the early hours of this morning.
