When out for a walk with her guardian, galeforce winds blew BiBi, a Maltese-shitz, right off Brighton Pier in Melbourne, Australia and into the icy waters below.
Bibi stuggled to stay above the water, as the currents and winds drove her further out to sea.
Bibi's guardian, Sue Drummond could only look on helplessly as her dog fought to stay above the angry waves.
Thankfully for Bibi and Sue, Raden Soemawinata was at the pier. He was attending a family ceremony to scatter his grandmother's ashes into the bay.
When he saw Bibi needed help, he stripped down to shirt, underwear and socks, and dived in to the ocean to rescue Bibi.
Bibi swam closer to Raden in anticipation of being rescued.
Bibi swam directly into Raden's arms and the pair made their way back to safey.
When told he was a hero, Raden told Melbourne's Herald Sun, "It was pretty cold and windy, but it wasn't such a hard decision to jump in, it wasn't such a great feat." The twenty-year-old joked, "I'm a part-time model, so getting into my jocks isn't so different to what I do for work."
Grateful for Raden's brave actions, Sue gave him a big hug when he and Bibi were back on the dock.
