text: A heavily armed Algerian jihadi who was preparing to attack churches in Paris on the orders is in custody this morning after being implicated in the murder of a young woman. The 24-year-old, named locally as Sid Ahmed Ghlam, had shot himself in the leg before his arrest by anti-terrorist officers in the 13th arrondissement in southern Paris on Sunday. This afternoon the Paris prosecutor said police found Arabic documents mentioning ISIS and Al Qaeda at the IT student's home, as well as evidence on his computer that he was in contact with a man in Syria 'who clearly asked him to target a church.' Sunday's arrest came just hours after the murder of Aurelie Chatelain, a 33-year-old mother and fitness instructor, who was riddled with bullets as she sat in her car in a car park in the Paris suburb of Villejuif. Investigators reportedly claim DNA evidence links Ghlam to her murder. Scroll down for video . Sid Ahmed Ghlam (pictured) had shot himself in the leg before his arrest by anti-terrorist officers . Killed: DNA evidence also reportedly links Ghlam to the murder of Aurelie Chatelain (pictured left and right), a 33-year-old mother and fitness instructor who shot dead in her car in a Paris suburb on Sunday morning . Gathered: This is the student residence  where Sid Ahmed Ghlam - a 24-year-old computer science student suspected of plotting imminent attacks on churches in France - had reportedly been living . French Interior Minister Bernard Cazeneuve today said: 'A terrorist attack was foiled on Sunday morning.' 'The police discovered an arsenal containing weapons of war, and a suspect was immediately taken into custody.' Victim: DNA tests reportedly link the arrested man to the murder of Ms Chatelain (pictured) on Sunday . Mr Cazeneuve said the suspect was found on a street in the 13th arrondissement of Paris with a bullet in his leg, and bleeding heavily. He originally claimed to be the victim of an attack by criminals, but officers followed the trail of blood to his car, where they found a Kalashnikov assaultrifle, and a Sig-Sauer automatic pistol. There were also stolen police armbands which would enable him to pose as a plain clothes officer. In Ghlam's student accommodation, detectives later found three automatic rifles, handguns, and bulletproof vests. There were also Jihadi flags and literature, false passports, and plans for attacks on 'one or two' churches in the Paris area. DNA analysis reportedly linked the arrested man to the murder of Ms Chatelain, who was originally from Caudry, in northern France. The arrested man was an Algerian national studying computer science in Paris, and was known to the intelligence services. The man had been considered a likely candidate to travel to Syria to fight with the Islamic State terrorist organisation, said Mr Cazeneuve, and was officially under surveillance. Tragic: Ghalm's arrest came just hours after the murder of Aurelie Chatelain (pictured), a 33-year-old mother and fitness instructor, who was riddled with bullets as she sat in her car in the Paris suburb of Villejuif . Statement: French Prime Minister Manuel Vall, left, and interior minister Bernard Cazeneuve, speaking to the assembled media about the thwarted attack after a cabinet meeting at the Elysee Palace in Paris today . Location: The 24-year-old, named locally as Sid Ahmed Ghlam, had shot himself in the leg before his arrest by anti-terrorist officers in the 13th arrondissement in southern Paris (pictured) on Sunday morning . The arrested man had moved to France in 2009, and was supported by his sister, who lives in the Paris area. Her home has since been raided by police too. It follows the Charlie Hebdo terrorist attacks in January, when three Islamist terrorists slaughtered 17 people in the city. They included cartoonists and journalists working for the notoriously anti-Muslim magazine, as well as police and four Jews who were targeted in a kosher supermarket. Two of the attackers, Saif and Cherif Kouachi, were both from Algerian backgrounds, while the third, Amedy Coulibaly, was from a Malian immigrant background. All were shot dead by police commandos following sieges.
