Manchester Bombing: Three more arrested in attack at Ariana Grande concert arena

Police arrested three more men tied to the suicide bombing at a concert arena in Manchester, England, that killed 22 and injured more than 100 others, the Associated Press reported.

The arrests came a day after police arrested a 23-year-old man in South Manchester, alleged to be tied to the attack.

The attack was carried out by Salman Abedi, a 22-year-old British national of Libyan descent, who died after detonating the bomb.

The Islamic State claimed responsibility for the attack. However, police are still determining whether Abedi acted alone as they assess the threat of another attack.
