LONDON (AP) — Police in Manchester say they have arrested three more men in connection with the suicide bombing at a pop concert that killed 22 people.
They said Wednesday the arrests had been made in the south of the city, where a day earlier a 23-year-old man was also arrested and a number of homes were searched.
British police and intelligence agencies are also working Wednesday to piece together the allegiances of the Manchester suicide bomber and foil any new potential threats, as the country’s law-and-order chief said it’s “likely” he did not act alone.
Home Secretary Amber Rudd said Salman Abedi, who killed 22 people and wounded dozens at an Ariana Grande concert Monday night in Manchester, had been known to security forces “up to a point.” Officials are examining his trips to Libya.
Britain on Tuesday raised its threat level from terrorism to “critical” amid concerns that the 22-year-old Abedi may have accomplices who are planning another attack. British soldiers have been deployed in place of police officers to guard high-profile sites such as Buckingham Palace and Parliament.
Abedi was born in Britain to a Libyan family, grew up in Manchester’s southern suburbs and attended the local Salford University for a time.
Police on Tuesday raided his house, using a controlled explosion to blast down the door. Neighbors recalled him as a tall, thin young man who often wore traditional Islamic dress and did not talk much.
British Prime Minister Theresa May Wednesday chaired a meeting of her emergency security cabinet group known as Cobra to deal with the intelligence reports about Abedi and concerns that he might have had outside support.
Police also raided and searched a property elsewhere in Manchester where Abedi’s brother Ismail is thought to have lived. A 23-year-old man has also been arrested as part of the investigation but officials have released no details about him.
Officials are probing how often Abedi had traveled to Libya, which has seen an eruption of armed Islamist groups since dictator Moammar Gadhafi was overthrown and killed in 2011.
France’s interior minister said Abedi is believed to have traveled to Syria and had “proven” links with the Islamic State group.
