Video report by ITV News Correspondent Chris Ship
Twelve people have been arrested in connection with the London Bridge attack, the Metropolitan Police Service has said.
It comes after at least four police vans were seen stationed behind a cordon outside flats in King's Road, Barking, and residents reported hearing bangs on Sunday morning.
Police confirmed on Sunday night that they were detaining seven women aged between 19 and 60 under the Terrorism Act following the raid.
Five men aged 27 and 55 were also arrested during the police operation - one of whom has since been released without charge.
Seven people were killed and 48 people injured after a van and knife attack at London Bridge and Borough Market late on Saturday evening.
The attackers were stopped by eight police firearms officers who fired an "unprecedented" 50 rounds, Assistant Commissioner Mark Rowley said.
A member of the public also received a gunshot wound.
One of those killed has been confirmed as a Canadian citizen and French authorities have confirmed a French national was also killed.
A number of the injured are suffering serious and life threatening injuries.
It was the third terrorist incident to hit the country this year following the recent Manchester and attacks.
Theresa May has condemned the "evil" ideology behind the attacks and urged the public to "go about their lives as they normally would".
The prime minister also warned of "a new trend in the threat we face as terrorism breeds terrorism".
"But it is time to say `Enough is enough,'" she added.

Mrs May also insisted that Thursday's General Election will go ahead as planned.
"As a mark of respect, the two political parties have suspended our national campaigns for today.
"But violence can never be allowed to disrupt the democratic process so those campaigns will resume in full tomorrow."
Eight minutes of carnage
The van was driven into pedestrians on London Bridge shortly after 10pm, before the attackers fled and began stabbing people in Borough Market.
