Manchester suicide bomber was in Germany days before the attack: Report

British home secretary Amber Rudd said Abedi “likely” did not act alone in the strike at the close of an Ariana Grande concert Monday night.

Salman Abedi, the British suicide bomber who killed 22 people at a music venue in Manchester on Monday, was in Germany four days before the attack, Sky News reported on Thursday citing German intelligence.

Abedi had been in Dusseldorf, 300 miles (482.8 km) west of Berlin, Sky said.

Investigators have said they believe he was part of a wider network of militants.

“I think it’s very clear this is a network we are investigating,” Chief Constable Ian Hopkins of the Manchester Police said as authorities raided British properties thought to be connected to Salman Abedi, the 22-year-old suspected bomber who grew up in Manchester and died in the attack.

British home secretary Amber Rudd said Abedi “likely” did not act alone in the strike at the close of an Ariana Grande concert Monday night and that he had been known to security forces “up to a point.” Meanwhile, officials probed possible travel by the alleged bomber, looking for clues to new threats.
