Manchester: A total of 16 people are in detention in Britain and Libya over the 22 May suicide bombing at a pop concert in the English city of Manchester by a British-born man of Libyan origin.
A teenage boy and a woman arrested by British police this week have since been released without charge, leaving 14 in British custody.
In Libya, the father and brother of the bomber, Salman Abedi, are also in detention.
Abedi reportedly returned from Libya only a few days before the attack which killed 22 people, including seven children under 18, but police are still trying to establish the extent of his wider network.
Here are the details of the arrests so far:
Tuesday, May 23
- Police arrest a 24-year-old man in the Chorlton area of south Manchester near where Abedi is believed to have lived. Police had earlier given the man's age as 23.
A witness told AFP that police shouted at the man to lie on the ground before taking him away. British media indicated that the man is highly likely to be Abedi's older brother Ismael.
The brother was described in media reports as "outgoing" compared to Salman, who was "very quiet".
Wednesday, May 24
- Police arrest three more men in south Manchester aged 18, 21 and 24, a short walk from the house where Abedi lived.
Omar Alfaqhuri, a neighbour who lives just in front of a house that was raided, said he saw "a massive deployment of police forces" during the nighttime arrest and a man he named as "Adel" handcuffed and taken away.
"They blocked the whole street," he said, adding that his neighbours were a "nice quiet family".
- An 18-year-old man, who police said was carrying a suspect package, is arrested in Wigan, a town near Manchester. No further details were given about him.
- Another man, 22, is arrested in the town of Nuneaton in central England, widening the British police probe beyond areas in and around Manchester.
- Libya's Deterrence Force, which acts as the police of the Tripoli-based Government of National Accord, arrests Abedi's father Ramadan, adding that it had already arrested his brother Hashem on Tuesday.
A spokesman said that the brother was aware of Abedi's attack plan and that both men belonged to the Islamic State group, which claimed responsibility for the attack.
Abedi's father reportedly protested his son's innocence in the hours before his arrest.
- In Manchester, a 34-year-old woman is arrested by police in an apartment block in Blackley, in the north of the city. She is later released without charge.
Thursday, May 25
- A 16-year-old boy is arrested in Withington, south Manchester. He is later released without charge.
- A 38-year-old man is arrested in Blackley.
Friday, May 26
- A 30-year-old man is arrested in Moss Side, an area of Manchester associated with social deprivation and gangs.
- A 44-year-old man is arrested in Rusholme, in the south of the city.
Saturday, May 27
- Two men aged 20 and 22 are arrested following a raid, involving a controlled explosion, at an address in Cheatham Hill, north Manchester.
Sunday, May 28
- A 25-year-old man is arrested in Old Trafford, to the east of the city.
- Later that evening, police arrest a 19-year-old man in the southwestern Gorton area of the city.
Monday, May 29
- Police arrest a 23-year-old man in the southern coastal town of Shoreham-by-Sea, more than 400 kilometres (250 miles) from Manchester, suggesting authorities are widening their net in the hunt for accomplices.
In addition, police raided a property in a southern Manchester suburb as they step up their investigation into last week's bombing that killed 22 people.
The attack, Britain's worst in more than a decade, was carried out by British-born extremist Salman Abedi, who detonated a powerful bomb at the exit of a concert by US singer Ariane Grande.
Several of the victims were children, the youngest being just eight. Scores were injured in the attack.
Police have been hunting for a network of people connected to Abedi, with Britain's interior minister Amber Rudd saying on Sunday there were potentially still members of the cell at large.
"The operation is still really at full-tilt in a way and so until the operation is complete we can't be entirely sure that it's closed," said Rudd.
Abedi's brother and father are being held in Libya.
On Sunday, police released photographs from security cameras showing Abedi on the night of the massacre, wearing jeans and trainers, a black bodywarmer and a baseball cap, with the straps of his backpack visible on his shoulders.
Britain has downgraded its security level from its highest level, but it still remains at "severe", meaning an attack is highly likely.
