Four people , including a policewoman , have been arrested over links to the attacks that terrorised Paris earlier this year , French police and security officials have said . The two officials said one man who was detained had ties to Amedy Coulibaly , the gunman who killed a policewoman on January 8 and then four more people at a kosher supermarket on January 9 before being killed by security forces . They added that the detained man 's ex-girlfriend , a policewoman who was suspended after peeking into his criminal file , was also in custody . Scroll down for video . The two officials said one man who was detained had ties to Amedy Coulibaly ( pictured ) Coulibaly was responsible for the siege at the kosher deli ( pictured ) on January 9 where he killed four people . The siege ended when Coulibaly was shot dead by police as they raided the premises . The officials , who spoke on condition of anonymity because the investigation was ongoing , had no details about the two others . It has been claimed the policewoman worked at Fort de Rosny-sous-Bois , in north east Paris , which is the location of a police intelligence centre . Le Figaro reported that she was suspended from her duties in early February . Coulibaly shot dead an unarmed policewoman on January 8 , before taking hostages at a Jewish supermarket in Paris the following day . That siege ended after he killed a further four people , before police stormed the building and killed him in a blaze of bullets . During the siege , Coulibaly had told French media that he had 'synchronized ' the attacks with the Charlie Hebdo killers , but failed to provide any further details . Detectives also allegedly discovered that Coulibaly filmed his attack on his assault on the kosher supermarket with a high-tech GoPro camera attached to his chest . It is understood the footage was then sent via internet from the hostage scene , but it has not been posted since . No-one besides three dead gunmen have been linked directly to the January 7 - 9 attacks at the satirical newspaper Charlie Hebdo and the market , which left 20 people dead , including the gunmen . Last month Islamic State published what it described as an interview with Coulibaly 's widow , Hayat Boumeddiene , claiming for the first time she was among extremist fighters . Boumeddiene is believed to have fled to Syria not long before her husband carried out the shocking attacks across Paris . Coulibaly 's attacks coincided with the masscare at the Charlie Hebdo offices perpetrated by the Kouachi brothers Said and Cherif . Brothers Cherif ( left ) and Said Kouachi ( right ) killed 12 people during the attack on the Charlie Hebdo offices . The pair arrived at the satirical magazine 's offices on the morning of January 7 and forced their way inside the building . The two arrived at the satirical magazine 's offices on the morning of January 7 and forced their way inside the building . Claiming to act in revenge for the publication 's perceived mockery of the Prophet Mohammed , they murdered 11 people . After fleeing north , the following day they were involved in a standoff with police in which they were both killed . Nobody with ties to the Kouachi brothers is in custody or has been formally sought since the attacks .
French police and security officials say four people have been arrested . One is linked to Charlie Hebdo , the Paris gunman who killed five people . Another , who is a policewoman , is thought to be one suspect 's ex-girlfriend . She stands accused of accessing his criminal file , French officials said . It is claimed she worked at a large police intelligence centre in north Paris . Authorities have not yet released details about the other two in custody .
