Instead, that evening, police say Butt rented a Renault van.
Butt, who police consider the attack ringleader, had been on bail after being arrested for fraud in a case in October of past year, police said.
Detectives investigating the London Bridge terror attack have made two further arrests, the Met Police have confirmed.
When investigators searched the van, they found a host of improvised weapons, including 13 wine bottles apparently fashioned into Molotov cocktails, as well as two blow torches.
It also emerged that multiple petrol bombs were found in the van used in the outrage, while a copy of the Koran opened at a page "describing martyrdom" was discovered in the east London bolthole where the three men plotted the attack. Local police revealed that the three had loaded the van with sacks of gravel, in all likelihood to increase the van's weight so that they could use it as a "battering ram" against the pedestrians. "People are absolutely determined to do everything they can to stop such an attack in the future".
He is thought to have driven the van, with Redouane and Zaghba in the back, into central London.
A total of 18 people have been arrested since the attack, with five remaining in custody.
Envoy Haley says US won't let the UN 'bully' Israel anymore
Rabbi of the Western Wall Rabbi Shmuel Rabinowitz and his wife accompany UN Ambassador Nikki Haley to the Western Wall. As she departed the Kosel plaza, she said, "I am moved by the warm reception that the Israeli public has given me".
Mr Cron said he feels safe and reflected on the response to the attack, saying: "Some of the heroes that came out of the attack".
Officers are particularly keen to hear from anyone who witnessed the white van targeting individuals on London Bridge, saw the suspects attacking members of the public or armed police engaging the suspects. "How did they know each other?" Once across they turned around and travelled back the way they came, before turning around at the top and setting off on their final deadly journey, ploughing into pedestrians as they went.
Each belt had three disposable water bottles covered in masking tape attached to them.
Police were called within two minutes and arrived eight minutes later, killing the attackers in what officers said was an "unprecedented" volley of 46 bullets.
The police and intelligence agencies have tried to prevent complex, high-tech plots such as those created to bring down commercial flights but now they are dealing with a rash of less complicated attacks on soft targets, she said. Police are also appealing for information about the "distinctive" pink "Ernesto" brand knives the men were carrying.
"There was no evidence uncovered of any attack-planning in relation to him", Haydon said.
"We will be going out as, we have always done, to get young people engaged in activities that positively contribute to society in Redbridge", he said. Police have installed security barriers running alongside the sidewalks at eight bridges across the River Thames, and Haydon said similar protection was being considered at other locations.
