India, Sept. 5 -- A 21-year-old BSc student from Madhya Pradesh, Surendra Singh Choudhary, popularly known as 'Bittu Tabahi', has drawn widespread attention for taking it upon himself to clean the polluted Ajnar River in Biaora. His efforts have now earned praise from former England cricketer Kevin Pietersen, who called his work "heroic" and said it deserved international recognition.

Taking to Instagram, Pietersen shared before-and-after pictures showing the transformation of parts of the river and praised the youngster for stepping in rather than waiting for others to act.
