Police have released the last photo taken of Mackenzie Crook's missing sister-in-law Laurel Aldridge as they appeal for help from the public, showing her facing away from the camera.
Ms Aldridge, 62, who has been described as "vulnerable" by police, was last seen leaving her home in West Sussex on the morning of Tuesday February 14.
A new photo shows Laurel wearing a grey puffer jacket, which police advised she may have with her, and dark blue trousers as her back is turned away from the camera.
An image released last week also showed the Pirates of the Caribbean actor's sister-in-law wearing a brown hat along with a maroon tartan patterned scarf along with a turquoise, zipped fleece.
It's understood she is likely to have been wearing the grey jacket on the day she went missing, police say.
Laurel is described as being around 5ft 4inches with grey/blonde highlighted hair and sometimes wears glasses.
After the release of the images, police are appealing for help from the public.
Sussex Police are asking anyone driving around the Arun area of West Sussex on and after February 14 to check their dashcam footage for sightings of Laurel.
A press release from police reads: "Officers are particularly keen for people driving in the area since Tuesday (February 14) to check their dashcam footage if they have used, but not limited to, the following roads:
"The A27 in both directions between Fontwell and Arundel. The A29 in both directions between Fontwell and Houghton. Anyone driving in the Slindon area. Anyone driving in the Walberton area.
"When reviewing the footage, if there is someone which matches Laurel’s description please report it to police online or call 101 quoting Operation Accrue."
Detective Sergeant Alan Fenn said: "We are continuing to pursue multiple lines of enquiry and would thank any members of the public who have provided information to us so far. We may have information which could place Laurel’s last known location. To be in that location it’s likely Laurel would have crossed a busy road where people would have been driving in the area at the time.
"I am urging people who were driving in this area or near to this area of Arun to review their dashcam footage to see if there is anyone who matches Laurel’s description.
"We have a dedicated officer who is in contact Laurel’s family and will continue to support them throughout this investigation. Please continue to look out for Laurel and call 101 with non-urgent information and 999 if this information is urgent quoting Operation Accrue.”
Information can also be reported to Crimestoppers anonymously on 0800 555111.
It comes after The Office star Mackenzie, 51, pleaded with the public to help find his missing relative.
Mackenzie has claimed that the disappearance of Laurel is "very out of character" in an emotional interview.
Speaking to ITV, the actor who has also appeared in Pirates Of The Caribbean said: "She left her house early Tuesday morning and she's not been seen since.
"That's in the Walberton area where a lot of people are looking in the local woodlands along the roads and stuff like that.
"I'd really like to appeal to people to go out into their back gardens and have a look in places where she might have taken rest."
He went on to add: "She's been missing out for three nights - we're entering the fourth one now so, we're obviously really worried.
"If I could appeal to everyone, even if they checked before, check again in likely places where she might have crept in to lay down for the night."
