In a heart-warming gesture, Polish javelin thrower Maria Andrejczyk auctioned off her silver medal, which she won in the recently concluded Tokyo Olympics, for $125,000 to fund a life-saving heart surgery of an eight-month boy.

The 25-year-old wanted to help a stranger following her medal-winning feat, and said on her Facebook page this was the first fundraiser she stumbled upon.

“It was the first fundraiser I entered and I knew it was the right one," she wrote on her Facebook wall on August 11 in her native language. The fundraiser was for a young Polish boy who goes by the name of Miloszek. He has a serious heart defect and requires surgery.

“He already has a head start from Kubus — a boy who didn’t make it in time but whose amazing parents decided to pass on the funds they collected,” she wrote on social media.
