A 31-year-old woman was assaulted and then robbed by another female outside a takeaway in Cleethorpes.
Humberside Police released CCTV images on September 6 of two people they want to identify in connection with a robbery and assault.
The incident happened on the High Street in Cleethorpes between 4am and 5am on Tuesday, August 4.
A pink iPhone, bank cards and an NHS ID card were stolen from a woman, who was sent to hospital with scratches to her neck, back and arm and with back pain.
While the incident was ongoing, a man approached the two women and indecently exposed himself. Police want to find him, but said it is not known if he was known to the female suspect.
The woman is described as in her 30s, of skinny build and claimed she was pregnant. She was wearing a spotted blue and white dress and possibly a headscarf.
The man is in his 20s, around six foot tall and was wearing a black t-shirt, blue shorts and trainers.
Anyone with information, or who recognises the pictured people, should contact Humberside Police quoting reference 16/89067/19.
