A 77-year-old man has been arrested and charged in connection with the deaths of a mum and son more than forty years ago.

Police had been investigating the 1976 disappearance of Renne and Andrew MacRae, which led them to a detailed search of Leanach Quarry, near Inverness.

They have now confirmed the arrest of a man in the north of England.

He is due to appear before Inverness Sheriff Court later today.

The bodies of Renee and three-year-old Andrew have not yet been recovered

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 enquiries, or at any time since 1976."
