LONDON (AP) - British police have arrested two more suspects over the London Bridge attack, and revealed that the carnage could have been worse had the terrorists succeeded in their goal of renting a larger truck, rather than a van, to mow down pedestrians.
The bloodthirsty gang was also shot dead before they could make their way back to the van where their petrol bombs were stored.
London’s Metropolitan Police said Saturday that they arrested a 27-year-old man and a 28-year-old man overnight in east London on suspicion of preparing acts of terrorism. Police have seven people in custody over suspected links to the three terrorists who killed eight people on and around London Bridge on June 3.
Police released details of their investigation Saturday as they appealed to the public for information, saying that Khuram Butt, believed to be the plot’s ringleader, originally tried to rent a 7.5-ton box truck. The intended truck was smaller but similar to the one used in the Nice attack last year that killed 86 people and injured hundreds in the resort town in the south of France.
After his payment was declined, Butt and his two accomplices rented a smaller van that they used to plow into crowds before they leapt from the vehicle and went on a stabbing rampage in an attack that left eight people dead and nearly 50 injured. It was the third deadly attack in Britain in three months.
After leaving the small white van, the men used 12-inch knives with bright pink blades, according to Dean Haydon, head of the Metropolitan Police’s Counter-Terrorism Command.
Police also disclosed that more than a dozen petrol bombs and two blowtorches were discovered in the van, and a copy of the Koran opened at a page “describing martyrdom” was found at one of the terrorists’ houses.
Investigators believe three victims were killed on the bridge, including one man who was thrown into the River Thames, before the terrorists left the vehicle and stabbed five people to death around London’s busy Borough Market, Haydon said. Police believe Butt was driving the van.
“When I come back to Butt trying to get hold of a 7.5-ton lorry — the effect could have been even worse,” he said.
Haydon said the men may have been planning even more bloodshed if they made it back to the van.
Police also found a number of office chairs, gravel and a suitcase in the van.
Detectives believe the gravel may have been placed in the vehicle to make it heavier, or as part of a cover to justify hiring it, while the chairs may have been used to convince family and friends they were moving furniture.
Butt, a 27-year-old Pakistan-born British citizen, and his two accomplices, Rachid Redouane, 30, who claimed to be Moroccan-Libyan, and Youssef Zaghba, a 22-year-old Italian national of Moroccan descent, were shot dead by armed police eight minutes after the first emergency call.
The three terrorists were wearing fake suicide belts consisting of plastic water bottles wrapped in gray duct tape.
Haydon described the pink knives as “pretty unusual” and appealed for anyone with information about where they came from to contact police.
Police raided Redouane’s small residence on Tuesday and said he had been renting it since April. This was the safe house where the attack was planned, police said. In the residence, police said they found an English-language copy of the Koran opened at a page describing martyrdom, pieces of cloth which appeared to match material wrapped around the petrol bombs and water bottles similar to those used in the fake suicide vests. Luggage straps, plastic retractable craft knives and rolls of duct tape were also found.
The question remains how the men met and knew one another, but police said Saturday they did not suspect a wider plot.
“It looks as if it is pretty much a contained plot involving the three of them, which is supported by the forensic evidence we’ve got back so far,” Haydon said.
Butt had been on bail after being arrested for fraud in a case in October, police said. He had also been repeatedly reported to police for violent behavior and trying to recruit young children to the Islamic State group.
But Haydon said “there was no evidence uncovered of any attack-planning in relation to him.”
Butt had been warned by police on two occasions — once for fraud in 2008 and once in 2010 for assault. Still, he did not have any criminal convictions.
Zaghba and Redouane had no criminal convictions or such warnings in Britain.
“From what I’m seeing, there is nothing that suggests at the moment that we got that wrong,” Haydon said, referring to Butt.
