Detectives are renewing appeals for information after an elderly woman was struck by a pellet in Chessington.
Police were called at 19:37hrs on Saturday, 10 February, to outside the North Star public house on Hook Road in Chessington, following reports of a suspected shooting and a woman injured.
Officers and the London Ambulance Service attended. A 74-year-old woman was found suffering an arm injury.
The woman was taken to a south London hospital with a broken arm. She remains in hospital and is continuing to receive extensive medical treatment for her injuries.
At this stage, officers believe the injuries were caused by a large pellet that may have been fired from a catapult or similar device.
Officers would like to speak with anyone who witnessed the unprovoked attack.
The victim's son said: "Mum was only a few hundred yards from her house - not only has she got this horrific injury, she now wonders how she can ever walk down that road again. Perhaps she was just in the wrong place at the wrong time, perhaps she was not the intended target.
"Luckily Mum was holding her scarf up to her face to shield it from the wind, as such her arm stopped the ball bearing from hitting her chest or throat, where her injuries could have been far worse. If anyone knows who did this please contact the police so they can stop them from hurting anyone else"
Anyone who witnessed the incident, or has information about an individual using such a weapon in the Chessington area, should call Kingston CID via 101 quoting CAD 6572/10Feb.
