This is the heartwarming moment a caring schoolboy selflessly unblocked a drain to stop it flooding the road during a rainstorm.<br /><br />The drenched youngster was pushing his bike without even a coat when he stopped at the drain which was overflowing with muddy brown water in Dong Nai, Vietnam, on June 16.<br /><br />When the homeowner who lives in front of the drain returned home, she was baffled to see that the water was draining properly without the usual debris in the grates.<br /><br />Ta Hong, 34, and her husband checked their CCTV and were touched when they saw the young boy scooping away the filth with his bare hands.<br /><br />Having performed the good deed he was seen calmly walking away, without need of any recognition.<br /><br />The woman was so overwhelmed by the random act of kindness that she posted the footage online to find the boy and give him a small reward.<br /><br />He was identified as Pham Trong Dat, 12, from a nearby school. He said that he had noticed the drains overflowing after being blocked with debris and just did it to be helpful.<br /><br />''That afternoon I cleared about 10 manholes that were full of garbage, I just clean them by hand,'' he said.<br /><br />''I've done it in the past whenever there was a big rain storm.''<br /><br />The incident was widely reported in local media and officials visited Pham Trong Dat at the Long An Secondary School.<br /><br />Pham Trong Dat's uniform and backpack matched those in the video and he was praised by teachers for his civic spirit.<br /><br />His teacher, Phan Thi Ngoc Mai , Principal of Long An Secondary School, said: ''Pham Trong Dat is a careful and meticulous boy who often helps people. He never asks for anything in return.<br /><br />''His hobby is collecting broken mechanical components and building new things them.''<br /><br />It later emerged that Pham Trong Dat's parents are divorced and he lives with his 15-year-old sister and and his grandparents. His grandfather suffered a stroke and no longer works and teh family struggly by in their rundown brick hut with a bamboo roof.<br /><br />The grandmother, Huynh Thi Thu, 68, said: ''My grandson is very happy to see that he has been praised by many people. It has made him feel very proud that he is viewed kindly in their eyes.''
