Verbijsterend: halve familie van de Manchester-terrorist blijkt jihadist - nu pas worden ze opgepakt (+update)

"Confirming that an off-duty female police officer was among the 22 people killed in the attack, Chief Constable Ian Hopkins said officers are investigating associates of Salman Abedi when asked if they are seeking a "bomb maker".

Meanwhile, Abedi's younger brother Hashem has reportedly been arrested in Tripoli, Libya, on suspicion of having links to the Islamic State group that claimed responsibility for the attack. Abedi's father has spoken for the first time since Salman's death to deny his involvement and said: "We don't believe in killing innocents. This is not us."

However, a Muslim community worker has told BBC News that members of the public called the police anti-terrorism hotline warning about Abedi's extreme and violent views several years ago."
