Police have released CCTV footage of a couple they believe could help them find missing Invercargill man Raymond Horn.
Horn, aged 68, vanished from his rest home on February 15 and has not been seen or heard from since.
One of the last sightings of him was in Queens Park where he was seen wandering between 10.20am and 11am.
The newest footage, released on Friday, shows a couple in the same park later the same day.
Senior Constable David Loader said the couple may have seen Horne and "be able to provide valuable information regarding his movements that day".
Anyone with information that can help us identify the couple in the CCTV footage is asked to contact Police on 105 and quote file number 210215/802
