A public appeal has been launched to find a 20-year-old woman from Sheffield last seen four days ago.
Ellie Skinner was last seen when she was dropped off at Asda at Manor Top around lunchtime on Thursday, November 17.
Police say they are 'growing concerned' for her welfare.
A South Yorkshire Police spokesman said: "There have been no confirmed sightings of Ellie since Thursday and she hasn’t been in contact with anyone, which for this length of time is out of character and her family reported her missing on Sunday.
"Ellie is 5ft 8ins and of a slim build. She has shoulder length brown hair which has a red tint to it and she usually wears it in a ponytail.
"She was last seen wearing black stretch jeans, a light grey hooded top and black trainers."
Call police on 101.
