Dad Died Trying To Save Toddler After Pushchair Rolled Into River

Dad dies trying to save toddler after pushchair rolls into river

A father died trying to save his toddler moments after posing with him on a river bank for a family photo.

Sun Wen watched in horror as his 18-month-old boy Lin Sun's pushchair rolled into a river and immediately jumped into the water to try to rescue him. But tragically they drowned before rescuers found them.

Sun had arranged the baby buggy by the river bank in Hangzhou, Zhejiang province, eastern China, for a picture to celebrate Tomb Sweeping Day, a Chinese holiday where families visit their ancestors' graves.

Sun Wen had positioned his son's pushchair on the riverbank to take a photo but it rolled into the water.

Sun - who could not swim - sank beneath the surface and spent 20 minutes under water before rescuers could reach him and his son.

One witness said: "He was taking photographs when the baby moved in the buggy and it just started rolling faster and faster down to the river.

"The water is deep and neither of them stood a chance."

A police spokesman said: "It's a tragedy. Either the brake failed on the pram or he forgot to set it properly."
