Two police officers jumped into the River Thames to rescue a young woman who was struggling after falling into the water.
Metropolitan Police was called to Portsmouth Road in Kingston at around 4.30pm on Friday (April 13).
A Met statement said: "Two officers attended and could see that a young woman had been swept a considerable distance after she apparently fell into the river and was struggling.
"Without hesitation the officers entered the water and rescued the woman and brought her ashore."
The officers provided first aid treatment at the scene before London Ambulance Service arrived and took her to a west London hospital, the Met said.
Her condition is stable, and her family has been informed and are with her, the statement added.
Inspector Richard Jordan from Kingston said: "Both of the fine officers who responded to this call, acted quickly and bravely to help save this young woman.
"Their quick thinking and dedication to serving the public is typical of so many hard working response team officers who work 24/7 shifts and respond to a wide variety of emergency calls everyday."
