One of the jihadists who killed at least seven people in the London terror attack before being shot dead by police reportedly has a baby who is just two weeks old.

On Monday, Scotland Yard named Khuram Shazad Butt and Rachid Redouane as two of the attackers responsible for the atrocity at London Bridge and Borough Market on Saturday night.

Police also confirmed that all 12 people arrested in the aftermath of the attack have since been released without charge.

Butt was a 27-year-old British citizen born in Pakistan. He appeared in a national TV documentary on Channel 4 last year in which he unfurled an Isis flag in the middle of a London park.

It is also thought he was twice reported to police amid concerns about his behaviour. One acquaintance said he contacted the anti-terror hotline but that police “never got back to him“.

Redouane claimed to be Moroccan-Libyan. Both lived in Barking, east London.

Assistant Commissioner Mark Rowley has admitted that Butt was known to the security services, but there was no evidence of “attack planning” by him.

It also emerged on Monday evening that Butt had recently become a father.

According to Rukmini Callimach, a reporter for the New York Times who specialises in covering terror groups such as Isis and al-Qaeda, a neighbour said that Butt had a new baby just a fortnight ago.

She added that Butt’s wife wore a face-covering niqab, but that his behaviour wasn’t what most people would associate with an Islamist extremist – for example, he liked to blast pop music from his car.

The 27-year-old extremist, who was also known as ‘Abz’, appeared on a documentary about British jihadis last year that aired on Channel 4.

In the documentary, he was filmed alongside notorious hate preachers, praying before an Islamic State (Isis) flag.

The attacker, who, along with two accomplices, was shot dead by police at the scene, was pictured wearing an Arsenal shirt during the attack.

Butt is also believed to have worked at a branch of KFC and, later, London Underground.

Some of those who knew him said his extremist views were well known, while others reacted in disbelief.

Erica Gasparri, an Italian mother of three who lived close to him, said she confronted him for trying to “brainwash” her children.

She said: “He was trying to radicalise the children, he would go down to the park and talk to them about Islam. He also came to the houses and gave the kids money and sweets during Ramadan.”

She added that she reported the information to police, who told her the information had been passed to Scotland Yard.

However, others described him as “polite and normal”, and said they were shocked to learn that he could have carried out the horrific attack.

One neighbour, Ken Chigbo, 26, a market analyst, claimed the terror suspect had recently asked him how to go about hiring a vehicle.
