Policeman Ahmed Merabet was the one above shot dead in the streets
Both Said, 34, and his brother Cherif, 33, were first arrested in 2005 as suspected members of the Buttes Chaumont – a group operating out of the 19th arrondissement of Paris and sending terrorist fighters to Iraq.
Cherif was convicted in 2008 to three years in prison, with 18 months suspended, for his association with the underground organisation.
He had wanted to fly to Iraq via Syria, and was found with a manual for a Kalashnikov – the automatic weapon used in Wednesday's attack.
After his short prison sentence, Cherif was in 2010 linked with a plot to free Smain Ait Ali Belkacem, the mastermind of the 1995 bombing of the St Michel metro station in Paris that killed eight people and wounded more than 100 more.
Belkacem was a leading members of the GIA, or Armed Islamic Army – an Algerian terror outfit responsible for numerous atrocities.
Said and Cherif, both orphans, were born in Paris but grew up in foster care in Renne, Brittany.
They returned to Paris aged 18, when they moved to a council estate in Paris's 19th arrondissement. During this time Cherif was arrested for both drug dealing and theft.
With no direction or aspirations, the pair were quickly taken in by a gang known as Buttes-Chaumont, run by two Imams from northern Paris, one of whom was Farid Benyettou, a janitor-turned-preacher.
