Prime Minister Theresa May previously said police have identified all the London Bridge attackers and, while one person was released without charge, 11 people remain in custody in connection with the attack.
Police shot and killed the three attackers within eight minutes of the initial emergency call about the attack that killed at least seven people.
Of the 48 people taken to the hospital following the violence that started on London Bridge and continued in Borough Market, officials said Monday that "36 are now being cared for in London hospitals with 18 remaining in a critical condition".
Police have arrested 12 people - seven women and five men - and searched six properties, four on Sunday and two on Monday. One of the arrested men and one woman have since been released.
Police believe Butt, Redouane, and the third accomplice were the assailants behind the attack, where a rented Renault van rammed into pedestrians on the London Bridge sidewalk.
She said the U.K.'s national threat level remained at severe on Monday, which "means that a terrorist attack is highly likely". May faced questions over cutting 20,000 police posts in her time as Home Secretary.
Metropolitan Police Commissioner Cressida Dick said Monday that the country needed to rethink police resourcing and strategy.
Jeremy Corbyn, leader of the main opposition party, called on May to resign over the issue, saying earlier that "you can not protect the public on the cheap", and promising to recruit another 10,000 police officers if he is elected into power.
On Monday evening in London, a massive crowd gathered at Potters Fields Park, adjacent to London Bridge, to hold a vigil and pay tribute to those slain and the survivors of the attack.
One of the victims in Saturday's attack was identified as Chrissy Archibald, a Canadian who had moved to Europe to be with her fiance.
"He used to be friendly but suddenly... he wasn't acting as normal".
Islamic State has claimed responsibility for the attack, although the relationship the two men had with the group is unclear.
"The security and intelligence services and police have stopped 18 plots since 2013, including five since the Westminster attack two months ago".
Butt's neighbors described him to The Independent as a "family man" who appeared to have worked a series of short-term jobs. We can not say more about them at this stage. "He was standing over there, I could see them from my window", Gasperri said.
