IS claims Nice terror driver was a ‘soldier’ Attacker was treated by psychiatrist in past

It also emerged yesterday that while Bouhlel had no known links with terrorists, unlike those behind previous attacks in Paris, he had been radicalised very recently.

Neighbours described him as withdrawn, saying he was “alone” and “silent”, but said they did not believe he was involved with IS.

A cousin of Bouhlel’s wife, Hajer Khalfallah, who had been subject to his domestic violence and was last week taken into custody for her own protection, insisted he was “not a Muslim”.

Walid Hamou said: “Bouhlel was not religious. He did not go to the mosque, he did not pray, he did not observe Ramadan.

“He drank alcohol, ate pork and took drugs. This is all forbidden under Islam.

“He was not a Muslim. He beat his wife, my cousin, he was a nasty piece of work.”

Speaking outside a high-rise block of flats where Bouhlel had previously lived with his wife and family, former friend Samiq, 19, who did not want to give his surname, also said the suspect was not a devout Muslim.

He added: “I never saw him going to the Mosque. He was not a Muslim. During Ramadan I saw him smoking.

“I never heard him speak about extremism, I cannot believe that he was a member of Islamic State.”

He said people thought Bouhlel had psychological problems.

“He was a little bit crazy,” he added, but the teenager admitted that he was shocked by what had happened.

It also emerged yesterday that Bouhlel had been given a suspended sentence in March following a violent altercation on the road.

His lawyer then, Corentin Delobel, said his client had appeared normal.

He added: “I could not say ‘he is a terrorist, he’s an Islamist, he’s a radical’. It could have been you or me.”

The apartment where Bouhlel is believed to have lived before the attack was a hive of activity as media from around the world descended on Route de Turin.

A view through the keyhole of the door to the flat showed the aftermath of a raid by police, with scattered belongings including a blanket, monitor and wicker chair on view.

Also visible in the open drawers were what appeared to be boxes of medication and a strip of tablets.

Meanwhile, officers carried out a raid at an address near Nice’s main train station and made two arrests of people known to the killer. A third person was also arrested at an address in Nice earlier in the morning.

Investigators have reportedly been told by those under arrest that he recently brought up IS, and he had stopped drinking alcohol.

Interior Minister Bernard Cazeneuve insisted Bouhlel was not known to the security services, adding: “We are faced with a new type of attack.”

The waterfront promenade in Nice re-opened at midday yesterday for the first time since Thursday’s attack.

There was a visible security presence across the city with soldiers patrolling the streets.
