Friends of Mr Madar had expressed shock at his arrest, while AP said officials in France were ‘unsure’ which brother chauffeured the reality TV star the night she was robbed in a rented apartment in the French capital.
Multiple firearms, including an automatic pistol, and £121,000 in cash were found during the raids that took place across Paris on Monday morning
One of those arrested is the chauffeur with the limo firm used by the Kardashian family in Paris, raising the possibility that the crime could have been an inside job

One friend said: ‘This is very strange. Michael is a really sweet guy. I would not be surprised if the police had got this one wrong.’
It is understood that Mr Madar was taken to a police station for interview yesterday morning where he was then arrested.
The arrested men are aged mostly in their 50s, 60s and 70s.
Pierre B – the 72-year-old alleged ringleader – was arrested after officers broke down the gate of his villa in Plascassier, a village near Grasse, in the south of France.
The age of the suspects has echoes of the 2015 Hatton Garden safe deposit robbery in London – carried out by a team of veteran British criminals.
A police source said: ‘The oldest suspect is 72, while others are in their 50s and 60s and some are well known to the police.’
The reality TV star had a gun pointed at her, her hands and feet bound with cable ties and was left in the bath after masked men with police badges on their jackets burst into her room at a hotel in the city’s exclusive 8th arrondissement.
Ms Kardashian, the world’s highest paid reality television star, was alone because her bodyguard, Pascal Duvier, was out at a nightclub with her sisters.
But three months since the heist, the gang – including ‘career villain’ Pierre B – are thought to have been rounded up.
All those arrested can be held for up to 96 hours before being charged or released.
Barrister Jean Veil said his 36-year-old client had been left deeply traumatised after being bound, gagged and threatened with death in the French capital last October.
Coordinated raids at 6am saw a total of 16 men including a ‘major thug’ arrested in the city, and also in the south of France
The arrests come three months after the reality TV star was tied up and robbed at gunpoint by intruders at her luxury Paris flat
‘I welcome this with great satisfaction,’ said Mr Veil, who said he was due to discuss details of the raids with Ms Kardashian when she woke up in Los Angeles last night.
‘These arrests are a nice surprise because on the one hand, it will perhaps make it possible to find the jewellery,’ said Mr Veil.
‘On the other hand, it puts an end to the outrageous speculation by some, who thought it was intelligent to pretend that this robbery was staged, or a publicity stunt organised by Ms Kardashian.’
Mr Veil indicated that Ms Kardashian would look forward ‘putting her nose up’ at those who had doubted her word.
During recent conversations, Mr Veil said Ms Kardashian ‘still showed some form of anxiety. I think she was recently shocked and had the opportunity to say so on television.
