DETECTIVES don't believe a man missing from Tamworth has accessed his bank accounts or his phone since he disappeared two-and-a-half weeks ago.
Police are still combing for clues in the mysterious disappearance of Alexander Schlack.
New CCTV has emerged of Mr Schlack walking on Marius Street, near the intersection of East Street, on May 24.
The footage shows Mr Schlack about 5.45pm wearing a light brown corduroy long sleeve shirt, black pants and a black puffer jacket.
Oxley Detective Inspector Jason Darcy told the Leader he bought the clothing from stores in and around Peel Street about 5.10pm that same day.
But since the Marius Street sighting, there's been no trace of Mr Schlack.
"Since May 24 there has been no sign of Mr Schlack and we again make a public appeal for help on his whereabouts," he said.
"There has been no evidence of activity in the form of bank accounts and phones or contact with family and friends from Mr Schlack, and police and family have concerns for his welfare."
Detective Darcy said police have been in touch with their Queensland counterparts, who have issued a public appeal in the sunshine state for the missing 48-year-old.
Police have been told Mr Schlack has connections to Agnes Water in the Gladstone region.
Mr Schlack lives in Narrabri but has a medical condition. Police have been told he was at Tamworth hospital from midday until about 3.40pm on May 24, but when he failed to contact family, police were alerted.
He was also seen at 4.20pm on the corner of Peel and Bourke Street on the same day, before he went down the Kmart end of Peel Street. Police have confirmed CCTV captured him walking at that time carrying a brown jacket.
One week ago, tens of thousands of people across Tamworth received a text message from NSW Police that police were searching for Mr Schlack.
It was the first time Oxley police have used the geo-alert technology.
Mr Schlack is described as being of Caucasian appearance, about 180cm tall with a thin build, brown/grey hair and was unshaven.
Anyone with information on Mr Schlack's whereabouts, or who might have seen him in the past two weeks, is urged to contact Oxley police on 6792 7199 or Crime Stoppers on 1800 333 000.
