Police in NSW are renewing an appeal for public assistance a year after a NSW man vanished from the Lake Macquarie area.
Patrick Thaidy was last seen at his home on Delasala Drive in Macquarie Hills about 12am on December 6, 2020.
The 60-year-old was later sighted along Macquarie Road at Cardiff at about 9.25am and again on Bayview Street, Warners Bay, around 10.45am.
Despite extensive searches for Mr Thaidy, he has not been found.
“Police and family members hold grave concerns for his welfare,” NSW Police said.
Mr Thaidy has dementia and diabetes.
On Tuesday, police will conduct further aerial searches using a drone in the area Mr Thaidy was last spotted.
A ground search will also take place.
Mr Thaidy is described as being 180cm tall with a slim build and thin grey coloured hair and a short grey beard.
He is frail, walks with a stoop and left home without his dentures.
Mr Thaidy was last seen wearing grey Everlast track pants, a blue Everlast long sleeve t-shirt and black shoes.
