‘Full tilt’ probe into bombing attack in Britain

LONDON — British police made two more arrests and stormed three more locations Sunday as they hunted for suspects in the Manchester bombing, while a government minister said members of attacker Salman Abedi’s network may still be at large.

Greater Manchester Police said two men — one 25 years old and the other 19 — were arrested in the city on suspicion of terrorist offenses.

Police say that 1,000 people are working on the investigation, trying to track down Abedi’s accomplices and piece together his movements in the days before he detonated a bomb at an Ariana Grande concert.

British police now have 13 suspects in custody — including Abedi’s elder brother Ismail — and have searched properties across Manchester.

Police have released surveillance-camera images of Abedi on the night of the attack that show him dressed in sneakers, jeans, a dark jacket and a baseball cap.

[...] security remained high at major events across Britain on Sunday, including the Great Manchester Run road race, where police armed with submachine guns protected thousands of participants and spectators.
