"He was arrested on suspicion of being concerned in the commission, preparation or instigation of acts of terrorism under Section 41 of the Terrorism Act 2000", the police said in a statement published late on Sunday.
Jackson said some of those arrested had offered "accounts which explain innocent contact with Abedi".
The 34-year-old said: "They were behind me so I couldn't see, one was standing basically beside me as I was huddled down in the corner".
In France, Paris Prosecutor Francois Molins said the man who attacked a policeman with a hammer outside Notre Dame Cathedral was a self-radicalized loner with a deep interest in Daesh (ISIS) propaganda.
Another arrest has been made in the investigation into the London Bridge attack.
Haydon provided unusually extensive details of last Saturday's attack, the deadliest in Londonsince suicide bombers killed 52 people on the city's transport network in 2005.
They say the attackers may have planned even worse carnage.
"I have not seen this tactic in the United Kingdom before where terrorists create maximum fear by strapping fake explosives to themselves", said police commander Dean Haydon, who is leading the investigation. The Metropolitan police also revealed that there were a number of petrol bombs in the van, as well as two blow torches, which the three attackers fortunately didn't get to use in their attack. The three terrorists who carried out the attack were identified as Youssef Zaghba, Rachid Redouane and Khuram Butt.
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.
At about 1730 GMT, the men drove to pick up the van before heading to Zaghba's home in eastLondon.
Two British counterterrorism sources told CNN that the arrest was part of an effort by British police and the MI5 intelligence agency to take known Islamist extremists off the streets by going after them for crimes unrelated to terrorism.
The phoney bombs were simply disposable water bottles wrapped in silver and black tape and attached to leather belts, although they were designed to create "maximum fear", police said.
The van also had office chairs and a suitcase. They are trying to build up a full picture of the movements of the three men in the days leading up to the attack.
Police are holding six other men in the assault on the London Bridge area that claimed eight lives. The interview was scheduled to take place at the end of this month.
