To avoid suspicion, the bomber made at least two separate trips to B&Q and Screwfix in Manchester before heading to Libya in April, The Times reports.
Yesterday it was reported a bomb-making factory had been found inside Abedi’s home in Fallowfield, South Manchester.
He is believed to have assembled the device at a city-centre flat rented on Airbnb on Monday before carrying out the atrocity.
On raiding the plush rental flat, cops discovered a huge stock of chemicals and bomb-making components.
Family and friends paid tribute to their loved ones as the last of the victims was named yesterday, while and cops continued the hunt for other members of the terror cell.
It is believed Abedi may have been given a crucial component for his device at a German airport en route to his terror mission.
Abedi flew to the city from Libyan capital Tripoli — via Istanbul — four days before the atrocity in Manchester.
