Police were called just before 5.20pm on Saturday. 21 October, to a report of a woman being seen walking in flood water along the A52 near Chaddesden.
The woman is described as between 5ft 6ins and 5ft 7ins tall, aged between 25 and 30 and has dark hair tied up. She was wearing a grey hooded top, salmon-coloured trousers, and was carrying a drawstring bag on her back. She was also carrying a drinking cup.
