A man has been missing from home for almost three months but his bus pass has been used every day since.
Robert Aucott hasn't been seen or heard from since April and police are becoming increasingly concerned for his welfare.
The 75-year-old is from Chester but his pensioner's bus pass has been used on routes around Liverpool each day since he went missing.
Officers are appealing to the public for information that could help locate him and have asked people who use the bus in the city to keep an eye out for him.
The pass was mostly being used on the number 14 route throughout June and July.
It is not clear which bus service the pass holder is using but people on the following routes should report any details to police.
Stagecoach 14 - Liverpool city centre to Tower Hill in Kirkby.
This route travels from town through Everton, Clubmoor, Gillmoss and Southdene.
Arriva 14 & 14X - Croxteth to Liverpool
This route travels from Liverpool, through Everton, Clubmoor, Gillmoss, and Knowsley Industrial Estate.
On Twitter, a spokesperson for Merseyside Police said: "Have you seen Robert Aucott? He's 75, from Chester & has been missing since April.
"Robert is known to frequent the Liverpool area & his bus pass has been reportedly used daily in June & July (in particular on the 14 route).
"If you've seen him please call on 01517773600."
