A man captured on CCTV footage in Australia, which also shows the last-known images of missing Irish woman Jill Meagher, has urged others on the camera footage to come forward.
Dan Gregson is one of six people visible on the video, which shows Jill walking home after leaving a bar in the early hours of Saturday morning.
Police are particularly interested in talking to a man in a blue hoodie who can be seen talking to her.
ABC reporter in Melbourne Stephanie Anderson said Mr Gregson did not see anything suspicious.
"One of the men (in the video) recognised himself and contacted police. He didn’t see anything suspicious, but he described everything he could and he said he hoped police will be able to see something he couldn’t to help in their investigation.
"He's also being very vocal in urging other people who appeared in the video to come forward."
