One of the images shows 33-year-old Sarah wearing the same coat as on the night she went missing.
Officers continue to ask people who live in the area, or who were there from 9.30pm on Wednesday, to check any CCTV or dashcams they may have and to come forward with any information.
Over 120 calls have so far been received from members of the public; information from which is currently being assessed by officers as part of their extensive enquiries. The investigation continues at pace, with 750 homes in the area visited; a wealth of CCTV recordings being examined; and searches of open spaces ongoing.
Detective Chief Inspector Katherine Goodwin said: “We’ve released two new images of Sarah as we continue to search for her. Please take a look at them and consider if you saw her on the night she went missing. I am interested in hearing from people who may have been in the area from 21:30hrs onward.
“We have seen an overwhelming response from the public not only in terms of information that has come into us; but also how social media is being used to share the appeals far and wide. I would like to thank everyone for the support they have provided. It is clear that everyone wants to help us to find Sarah safe and well.
“We have seized a number of CCTV recordings but we know that there are likely to be many more out there. Please, even if you’re not sure, check your doorbell or CCTV footage just in case it holds a clue. I’m also asking delivery drivers or anyone with dashcam footage who would have been in the Poynders Road area at approximately 21:30hrs on Wednesday to come forward.
“We have committed significant resources to this investigation, with assistance coming from across the Met. I want to remain clear that at this time we have no information to suggest that Sarah has come to any harm and we retain an open mind as to the circumstances. We share the wish of her family and friends to have her back safely with her loved ones.”
Sarah had been at a friend’s house in Clapham on the evening of Wednesday, 3 March. At approximately 21:00hrs she left the property in Leathwaite Road through a back gate onto the A205 South Circular and began walking to her home address in Brixton.
She is thought to have walked across Clapham Common and was expected to arrive home approximately 50 minutes later. It is unclear if she returned to her home address. She has not been seen or heard from since.
At around 21:30hrs on Wednesday, 3 March she was spotted on CCTV walking alone on the A205 Poynders Road, from the junction with Cavendish Road, in the direction of Tulse Hill.
The investigation continues to be treated as a missing person’s enquiry but due to its complex nature and concerns for Sarah’s welfare, it is being led by the Met’s Specialist Crime Command.
Anyone who has seen Sarah or who has information that may assist the investigation should call the Incident Room on 0208 785 8244.
Information can also be provided to detectives using the Major Incident Portal or by calling Crimestoppers, anonymously, on 0800 555 111.
Superintendent Kris Wright, from the Met’s Central South Area Command Unit which covers Clapham, said: “I know that Sarah’s disappearance is weighing on people’s minds and the local community is, of course, concerned about her and may even feel worried.
“I want them to know that they should expect to see more police officers on patrol in the area as we continue to search for Sarah and talk with the community. If you want to approach them about any concerns you have, please do so. We are here to support the community and we genuinely want to help in any way we can.”
