A £10,000 reward has been offered for information leading to the conviction of a gunman who robbed a Kent woman awarded a £48m divorce settlement.
Police said one of Mrs Charman's sons found her after the theft
Beverley Charman was tied up by a man wearing a balaclava at her £2.75m home in Sevenoaks, and robbed of her jewels.
Mrs Charman, 53, was shaken, but unhurt, after the robbery on 9 March.
Kent Police have renewed their appeal for information about the burglary following the announcement of the reward by insurers for Mrs Charman.
Jewellery worth several hundred thousand pounds was taken from her house, which is on a private road surrounded by high walls and electric gates.
Mrs Charman was robbed at her house in Sevenoaks
Mrs Charman, who is the ex-wife of insurance magnate John Charman, was alone in the house when the man broke in and threatened her with what could have been an imitation gun or a BB gun.
The robber was described as white, aged 18 to 26 years old, and wearing dark clothing.
A spokesman for Mrs Charman's insurance company said the ordeal had been very frightening for her.
"Insurers are keen to assist the police in catching the person responsible for this crime.
"Knowing that this man has been apprehended would provide some comfort to Mrs Charman, and may prevent this happening to another innocent householder," he said.
Last year, Mrs Charman was awarded £48m in what was thought to be the biggest divorce settlement in Britain's legal history.
