All 12 of the people arrested by officers investigating the London Bridge terror attack have been released without charge, Scotland Yard said.
Seven women and five men were arrested in Barking on Sunday following Saturday's atrocity which left seven dead and 48 injured.
A 55-year-old man and 53-year-old woman were released on Monday. The remaining 10 people - six women aged between 19 and 60 and four men between 27 and 55 - were released later in the day, meaning all 12 have now been released without charge.
The arrests were made after police raided properties in Barking on Sunday and two on Monday in Newham and Barking.
It comes as police identified two of the three attackers as Khuram Shazad Butt, a 27-year-old British citizen born in Pakistan, and Rachid Redouane, who claimed to be Moroccan-Libyan.
Butt was known to the security services, but there was no evidence of "attack planning" by him, according to Scotland Yard.
A third man has not yet been named by police.
All three were shot dead at the scene of the attack within eight minutes of the first 999 call.
