Three more arrests have been made in connection with the deadly suicide bombing at an Ariana Grande concert in Manchester, England, Monday, that killed 22 people including children, authorities said today.

The three men were arrested after police executed search warrants in South Manchester, the Greater Manchester Police said today.

Police also announced Tuesday that they had arrested a 23-year-old man in connection with the attack.

The news of three more arrests comes one day after U.K. Prime Minister Theresa May raised the country’s threat level to critical — the highest of the United Kingdom’s five threat levels — indicating that another attack may be imminent.

Investigators on Tuesday identified 22-year-old Salman Abedi as the suspected suicide bomber behind the attack. He died at the scene.

ISIS has since claimed responsibility for the bombing.

Officials said 119 people went to hospitals after the bombing; 64 injured people are currently being treated and 20 of those people are in critical condition.
