Opening the prosecution on Tuesday, Duncan Penny QC told the court Hashem was “just as guilty” of the murder of men, women, teenagers and a child who died in the attack.
Salman Abedi detonated a “homemade improvised explosive device” outside an Ariana Grande concert on 22 May 2017, the Old Bailey heard.
His brother Hashem Abedi is standing trial at the court for his role in the attack which killed 22 people.
The 22-year-old denies their murders and the attempted murder of others.
The jurors weretold about a man, who was an acquaintance of the defendant, was researching ‘sulfuric acid’ (sic) at a cost of £69.36 on March 13, 2017.
On that date the defendant was said to have texted his contact ‘send the bank details’, the jurors were told.
Some £70 cash was deposited into the man’s bank account at at branch of Barclays on Stockport Road in Longsight, the jurors were told.
A mobile ending 7132 attributed to the defendant was ‘cell-sited in the vicinity of that bank’ at that time, said the prosecutor.
The number later calls the contact, the court is told. The prosecutor told the court about an occasion two days later on March 15, 2017, when a newly created Amazon account of another acquaintance of the defendant was used to purchase ten litres of sulphuric acid.
There was evidence that £140 was paid into the contact’s bank at Lloyds TSB in in Manchester, according to the prosecution.
The jurors are then told about alleged efforts to source another ten litres of ten litres of sulphuric acid from using the same account later the same day.
The Crown say the defendant was involved in the sourcing of two of the three precursor chemicals used to making TATP explosives, sulphuric acid and hydrogen peroxide.
The trial has resumed here in court 2 and the prosecutor, Duncan Penny QC, is continuing to deliver his opening address.
He is continuing to focus on the defendant’s alleged attempts to source chemicals for use in the bomb between January to April 2017.
The jurors are told about Hashem Abedi’s efforts to approach a man he knew. The jurors are reminded that by then the defendant had already allegedly sourced five litres of acid on March 9.
The man, who cannot be named for legal reasons, was said to have been told by the defendant that the acid he was asking him to source was for a battery for a generator in Libya.
Hashem Abedi told the man that his brother had spilled some and it needed to be replaced.
The court heard the man attempted to purchase sulphuric acid for £76 for the defendant using his Amazon account but the purchase was declined due to a lack of funds. The man asked his father for help but he said ‘no’ and explained acid could be used in the manufacture of explosives, the jury was told.
The court heard that no purchase was ever completed.
Hashem denies conspiring with his brother to cause an explosion.
The trial was adjourned until Thursday morning after Mr Justice Jeremy Baker told jurors the defendant had told his legal team he felt unwell.
The judge said that after an hour of the hearing Mr Abedi was “feeling worse not better now and is in some pain” and would need medical attention.
