LONDON (Reuters) - British police arrested two 20-year-old men in Manchester on Wednesday in connection with last month's suicide bombing that killed 22 children and adults attending a concert by U.S. singer Ariana Grande, police said on Wednesday.
One was arrested overnight when police searched an address in the city, while the other presented himself voluntarily at a police station.
A total of 21 people have been arrested so far in the investigation into the suicide bombing. Twelve were released without charge and nine remain in custody.
