Early on Monday a man, 23, was arrested in Shoreham-by-Sea, West Sussex, on suspicion of terrorism offences.
Police on Monday arrested a 16th person in connection with the Manchester suicide bombing, the deadliest attack in Britain for 12 years.
A total of 16 people have been arrested in the investigation, however, two of them, a woman and a teenage boy, have since been released without charges.
Prime Minister Theresa May said developments in the investigation into the bombing meant that intelligence experts had chose to lower the threat level from its highest rating "critical", meaning an attack could be imminent, to "severe".
In the Libyan capital Tripoli, Abedi's younger brother 20-year-old Hashem and their father, Ramadan, are being held by special forces linked to the country's interior ministry.
It has emerged it was alerted to his extremist views at least three times.
Police have identified the attacker as 22-year-old Salman Abedi, a Manchester native, and are working to piece together his movements in the final weeks before the bombing as well as who else may have been involved.
Greater Manchester Police have made an appeal to the public for information about his movements since 18 May, when he returned to the United Kingdom from overseas.
Abedi was known to British security services before the bombing, the government has said, but Rudd declined to comment on exactly what had been known about him. Ismail Abedi was arrested shortly after the terror attack on Monday and remains in police custody.
"The intelligence services are still collecting information about him but I wouldn't rush to conclusions, as you seem to be, that they have somehow missed something", Rudd said. A spokesman said that the brother, Hashim, was aware of Abedi's plans to attack.
Greater Manchester Police said they had also executed search warrants at addresses in the Whalley Range area of Manchester and in Chester overnight.
Armed police patroled among spectators at the Great Manchester Run, the larged-scale event to take place since the bombing.
A huge round of applause for the emergency services followed a minute's silence for the victims and casualties.
Runners then set off under the banner #RunForManchester wearing yellow ribbons and Manchester bee symbols, while "I heart Manchester" signs were dotted around the city.
