A man suspected of being a ringleader of the Hatton Garden heist is a Cambridge physicist's son, it has emerged after police swooped on Great Shelford.
Michael Seed, 57, who was known only as Basil, was held after police raided his flat in Islington, north London, on Tuesday morning.
Mr Seed was born in Cambridge in in 1960 and his birth certificate states his father John's occupation as being “physicist”.
It is understood he passed away in 1972.
The news comes after Met Police descended on a home in Hinton Way, Great Shelford yesterday (March 28) and according to one witness, they had been there for two days.
Philip Stott, prosecuting at Westminster Magistrates' Court, said: "The charges relate to the burglary of the Hatton Garden Safe Deposit company over Easter weekend in 2015."
James Reilly, defending, said: "He works as a jeweller – he fashions jewellery. He had no knowledge or belief of involvement with the burglary."
Mr Seed spoke only to confirm his name, date of birth and address during a short hearing where he was remanded in custody, reported The Mirror.
The balding defendant listened intently to proceedings as the case against him was outlined.
He was charged on Wednesday with one count of conspiracy to burgle and one count of conspiracy to conceal or disguise criminal property.
Wearing a smart Barbour style brown jacket, a blue chequered shirt and jeans, Mr Seed was remanded to appear at Woolwich Crown Court next month.
What happened in Great Shelford?
Police cars were stationed in Hinton Way as officers searched the property.
Around four unmarked cars were reportedly also at the scene.
Several police vans, cars and scenes of crime officers were at the scene along with detectives and the back garden was taped off.
They may have been searching a pond behind the property, according to a neighbour.
The neighbour, who didn't wish to be named, said: “The police havent told us anything about why they are there.
"I know that a lady in her 70s lives there alone and has a dog. I havent seen her for a couple of days but the police did say she was alright.”
Forensic teams wearing white suits were also spotted in the village, as well as officers with metal detectors and search equipment.

Another witness at the scene reported seeing a man leave the house with a metal detector.

One of biggest heists in UK history
During a previous trial connected to the Hatton Garden heist, jurors heard that a team member known only 'Basil' had not yet been brought to justice.
It is believed Seed is this missing member of the gang.
Six men have already been jailed for their part in the raid over Easter weekend in 2015.
Disguised as workmen, they entered through a lift shaft and used a heavy duty diamond-tipped drill to cut a hole through the vault wall which was big enough for two men to squeeze through.
The gang then raided 73 safety deposit boxes, stealing valuables including gold, diamonds and sapphires.
The raid was one of the biggest in UK history.
