A woman has died at UHG, ten days after the car she was a passenger in entered the water at Menlo.
At around 7am on Friday March 15th, the car collided with a wall and entered a flooded turlough.
The woman, aged in her 30s, was a front seat passenger, while the driver was a man aged in his 40's.
Both were rescued and taken to UHG, but the woman was described as being in critical condition - and she's now passed away from her injuries.
Gardaí are now appealing for witnesses, particularly those with dash-cam footage, who were travelling in the Menlo area between 6am and 7am on Friday, March 15th.
