The landlord who allowed ISIS killers responsible for the Paris attacks to hide in his flat is a convicted killer and notorious gangland leader, it emerged tonight.

News of Jawad Bendaoud's conviction for stabbing a teenage victim to death came as he was remanded in custody for a fourth night in a row.

He has admitted lending his rundown apartment in the northern suburb of St-Denis to the ringleader of the massacres that left 130 people dead on November 13.

It has since been revealed landlord Jawad Bendaoud is a convicted killer who was jailed for killing a 16-year-old. Pictured is the scene outside the property following Wednesday's shootout

Three suspects including ISIS operative Abdelhamid Abaaoud and his cousin Hasna Ait Boulahcen were killed when police commandos raided the apartment early on Wednesday morning.

Ait Boulahcen was blown to pieces by an unidentified third man, who let off explosives tied around his body as police stormed towards the building.

In 2008, Bendaoud, who is in his 30s, was sentenced to eight years in prison for killing a 16-year-old college student with a large meat knife.

The pair had been 'arguing over a mobile phone' and Bendaoud 'insisted he was acting in self defence', said a legal source in Paris.

'Bendaoud avoided a murder charge and served relatively little time in prison for manslaughter before being released,' the source added.

Bendaoud was convicted at Bobigny criminal court in November 2008 for 'deadly assault and wounding causing accidental death' after killing his 'best friend', a 16-year-old identified as David.

The attack happened on Boxing Day, December 26th 2006, on the Rue de Corbillion in St-Denis.

The pair had a violent argument, which ended in fighting, and David ended up being cut in the throat by the meat knife.

When Bendaoud was released from prison, David's mother said Bendaoud 'risked hurting other victims'.

Chillingly, the attack on the youth took place in Rue du Corbillon - the street in which the flat which was to became an ISIS hideout was situated.

It is just a few hundred yards from the Stade de France, where the Paris attacks started with three suicide bombers blowing themselves up just outside the stadium during a France-Germany football international.

Bendaoud was released in September 2013, and soon became 'the boss' of Rue Corbillon.

Not only was he linked to drug deals, but he was the 'strong man' who 'sorted out' tenants who could not pay their rent.

Another source who knows Bendaoud describes him as 'violent and dangerous', and well known for being a 'gang leader' in an area notorious for its drug trade.

Eight people were arrested during Wednesday's police operation, including Bendaoud and a woman who was with him. All have now been released apart from him.

Bendaoud told journalists at the scene he had no idea his guests were jihadis, before being handcuffed and led away by police who overheard his comments.

He said on Wednesday: 'A friend asked me to put up two of his friends for a few days.

'I said that there was no mattress, they told me they just wanted water and to pray. I was asked to do a favour, so I did. I didn't know they were terrorists.'

The Saint-Denis flat at the centre of the investigation is believed to have been a squat Bendaoud rented out from time to time, and it has been linked with drugs.

Under French anti-terrorism laws, Bendaoud can be held in custody up to six days before being charged or released.

It was Hasna Ait Boulahcen who led Abaaoud and the third man to the apartment owned by Bendaoud.

Ait Boulahcen took the men to the apartment in Saint-Denis, and police launched their assault at 4:20am the next morning

The second legal source said a witness had reported seeing Ait Boulahcen with two men, one of whom resembled Abaaoud, after the attacks on November 13.

The 26-year-old woman was immediately placed under surveillance, with her home and mobile phone bugged.

On Tuesday she was seen talking to a man in what the source believes was a conversation to negotiate the accommodation of Abaaoud and a second man.

She then went to pick up the two men, who were hiding at an industrial site in nearby Aubervilliers.
