There has been no trace of Lincoln woman Emily Holloway since she was reported as missing more than a week ago.
Lincolnshire Police, who are also working with forces in Nottinghamshire, are continuing their investigation into her disappearance.
As previously reported, Emily was last seen when she was dropped off by a taxi in Newark, near Waitrose, in the early hours of the morning on Tuesday, December 2.
Enquiries have been carried out in Newark in the area of the train station and Waitrose, which are close to the River Trent.
Emily is described as 5ft 9” tall, of medium build, with short dark hair and blue eyes. She was wearing dark jeans, a maroon jumper and a red mac coat.
It is believed she does not have any personal possessions with her such as her phone or bank cards.
