Police are appealing for information after the disappearance of a man on June 6.
Thomas was last seen on Birkleigh Walk, Bolton, at around 6pm on that date.
He is described as a white male, around six feet tall, with a medium build, light brown hair, a brown/ginger beard, blue eyes, tanned skin, and a wrinkled forehead.
Police say he may be wearing a Montreal teal green zip windbreaker.
In a statement police said: "Officers are still appealing for help to find Thomas from Bolton.
"He is believed to have been seen in the Halliwell area earlier this week.
"He also may have travelled to Bradford.
"Anyone with information is urged to call us on 0161 856 5511 quoting log 1517 of 18/06/26.
"Officers are becoming increasingly concerned about him and want to make sure he is safe and well."
This is the second appeal police have issued for Thomas this week, as police are becoming increasingly concerned.
There was a potential sighting of him this week in Halliwell.
