France has decided to prosecute four men, who were detained recently, for aiding the Kosher shop gunman, Amedy Coulibaly.
The investigators found that they had aided Coulibaly in carrying out the deadly terror attacks in Paris.
The four detained were brought before a judge on Tuesday, who decided that the men should face possible charges of providing logistical support for the gunman, AFP reported.
Aged 22, 25, 26 and 28, they were among the 12 detained in police raids on Friday, following the deadly attacks by the Islamist radicals that killed 17 in and around Paris. Three women detained in the raids were freed on Saturday and five men were released overnight on Tuesday.
Coulibaly took hostages at a kosher supermarket in eastern Paris on 9 January, where he killed four French Jews before he was gunned down by the police. He is also suspected of shooting dead a policewoman the previous day just outside southern Paris.
In a video that appeared following his death, Coulibaly swore allegiance to Islamic State (ISIS) and claimed he planned the attack with Cherif and Said Kouachi, two brothers who began the three days attack on the satirical weekly, Charlie Hebdo.
