LONDON (AP) — The carnage of the London Bridge attack could have been worse: One of the attackers tried to rent a larger truck that could have killed more people, but his payment was declined. The bloodthirsty gang was also shot dead before they could make their way back to the van where their petrol bombs were stored.

In a rare glimpse into the weeklong investigation, police released details on Saturday that showed Khuram Butt originally tried to rent a 7.5 ton 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 people injured. It was the third such 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.
