A 77-year-old man has been charged in connection with the disappearance of Renee Macrae and her son Andrew more than four decades ago.
The man was arrested in the north of England by Police Scotland detectives and is expected to appear at Inverness Sheriff Court later today.
A detailed forensic search of Leanach Quarry, near Inverness, continues and no trace of Renee and three-year-old Andrew has been found.
Detective Inspector Brian Geddes said: “This is a significant development in an investigation which started when Renee and Andrew disappeared in November 1976.
“Their disappearance has had an unimaginable impact on the lives of Renee and Andrew’s family and friends for several decades.
“This has also been felt keenly in Inverness, but also across Scotland and beyond.
“Police officers and staff from across the country, as well as a number of partner agencies and contractors, have put an enormous amount of work into this investigation from 1976 to the present day, allowing us to reach this point.
“The remains of Renee and Andrew have not been recovered, however the searching of a large quantity of material removed from Leanach Quarry continues.
“I would like to thank everyone who has assisted the investigation, whether during our recent inquiries, or at any time since 1976.”
