The home secretary would not comment specifically on what the security service knew about Abedi, but insisted it was right for MI5 to review its processes because "the threat is always changing".
Britain's MI5 intelligence service launched an internal inquiry on Monday into whether vital clues were missed in the run-up to the Manchester suicide bombing, as police arrested another man in connection with the attack.
"I think it is the right first step".
British-born Abedi, 22, blew himself last week at the Manchester Arena indoor venue at the end of a concert by United States pop singer Ariana Grande, attended by thousands of children and teenagers.
Earlier, there were searches in Whalley Range, Manchester and in Chester and Shoreham-by-Sea, West Sussex, where a 23-year-old man was arrested on suspicion of terrorism offences.
Britain's official terror threat level was set at critical in the days after the attack, but was downgraded Saturday to severe.
It was while at Manchester College that two people who knew Abedi have confirmed they made separate calls to an anti-terrorism hotline to warn the police about his extremist views.
"We need to put our efforts into protecting young people", she told BBC News.
The Mail on Sunday also cited a source saying USA federal agents had been investigating Abedi since the middle of 2016 and had flagged up concerns to MI5.
"Did you see Abedi with this suitcase between the 18 and 22 May 2017?" This image was taken from CCTV in the city centre on 22 May.
The public are being asked to contact the police immediately if they see the piece of luggage, which officers have no reason to believe contains anything risky but are asking people to be cautious.
Operation Temperer, which involved the deployment of armed troops on patrol alongside police, will be wound down on Monday night, at the end of the holiday weekend.
Manchester Victoria station will reopen on Tuesday, British Transport Police have said.
The suitcase was not used in the attack, which was carried out when Abedi detonated an improvised bomb minutes after the concert ended, Greater Manchester Police Detective Chief Superintendent Russ Jackson said.
Britons head to the polls in 10 days' time to elect a new government.
From 2009 to 2016, the number of police officers fell by nearly 20,000, or around 14 percent, according to the independent Institute for Fiscal Studies think tank.
Authorities are now handling 500 terror-related investigations into 3,000 individuals, with another 20,000 people on the radar posing a "residual risk".
Abedi was also pictured with the suitcase in the Wilmslow Road area of south Manchester, which is close to where several subsequent police raids have taken place.
