Grande, 23, said in a message on her Instagram account that a date for the concert had not yet been worked out.
"The investigation is making good progress and we know the last places Adebi went was a city centre flat and from there left to make his way to the Manchester arena", police said. "A search is now on-going".
A 16-year-old boy and a 34-year-old woman who had been arrested were released without charge, police said.
The total number of arrests related to the attack have gone up to 14. British Transport Police announced the measure in a bid to "disrupt and deter criminal activity" on the rail network after the United Kingdom terror threat level rose to critical in the wake of the Manchester attack.
A severe threat means an attack is "highly likely", according to the scale set by Britain's Joint Terrorism Analysis Centre.
Corbyn, a veteran anti-war campaigner, said foreign policy was not exclusively to blame for terrorism but he would deploy troops overseas only "when there is a clear need", distancing himself from the interventionist approach that has seen Britain join the United States and other allies in military action in Iraq, Syria, Libya and Afghanistan in recent years.
US Secretary of State Rex Tillerson met United Kingdom foreign secretary Boris Johnson in London today and said the US took "full responsibility" for the leaks. According to TV news reports, Abedi worked as a "pawn" for a bigger terrorist network.
A suicide bomber killed 22 people and wounded scores of others minutes after Grande's concert at the Manchester Arena ended on Monday night. Abedi was known to United Kingdom security services, but his risk to the public remained "subject to review", according to reports.
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.
Hundreds of soldiers have been sent to replace police at high-profile sites including Buckingham Palace and Parliament, and police armed with submachine guns are being deployed in city centers, transit hubs, tourist areas and major events.
