Police have swooped on the home of the man they believe carried out the horrific terror attack at the Ariana Grande concert in Manchester.
Authorities named Salman Abedi, 22, as the man who detonated an improvised explosive device inside Manchester Arena at the end of the US pop star's concert on Monday night.
The bomb blast killed 22 people and injured a further 59. Mr Abedi also died in the explosion.
Officers blew the door off his red-brick, semi-detached home in the Manchester suburb of Fallowfield on Tuesday in a controlled explosion designed to give them safe access to the property.
Inside, police found a disturbing clue. Forensic officers were pictured carrying out a copy of a booklet entitled "Know Your Chemicals".
