NSW Police have called in the Westpac Rescue Helicopter to assist in a search to find a 60-year-old man missing in the Macquarie Hills area. 

The Helicopter will conduct an aerial search of the area and assist local ground rescue crews in their search to find Patrick Thaidy. 

He was last seen at his home on Delasala Drive, Macquarie Hills around 12am last Sunday, 6th December. 

Mr Thaidy is described as being 180 centimeters tall, with a slim build. He has thin grey-black coloured hair in a crew style cut, and a short grey beard. He walks with a stoop and is frail. 

He was last seen wearing grey Everlast track pants, a blue Everlast long sleeve t-shirt, and black shoes. 

Mr Thaidy has dementia and diabetes, and also left home without his dentures, so his appearance will vary from the supplied image. 

Anyone who has seen Patrick Thaidy, or knows of his whereabouts is urged to contact police.
