POOL SCUBA DIVER
During the preliminaries for the 100-meter women's backstroke on Sunday, American swimmer Kathleen Baker lost one of her signature pearl earrings that she wears for each of her races.
The 19-year-old swimmer on social media called for her competitors to keep an eye out for the missing piece of jewelry that was lost in the depths of the Olympics pool.
While her fellow swimmers might have swum too fast to notice the accessory lying at a depth of ten feet, a scuba diver in full gear went down to search for the earring.
The diver recovered the pearl at the bottom of lane 3, where Baker was swimming, at around the 15-meter mark. The earring was returned to her before the medal race on the next day when she took the silver medal after coming in after Hungary's Katinka Hosszu.
Reuters reporter Mark Trevelyan also noticed a diver entering the Olympic waters to fix cameras set at the pool bottom.
