Police say Liverpool attacker bought bomb parts for 6 months

The suspect who was killed in a Liverpool taxi explosion spent at least six months buying components for a bomb and appears to have acted alone, British police said Wednesday.

Emad Al Swealmeen, 32, died when a blast ripped through the cab in which he was a passenger as it pulled up outside Liverpool Women's Hospital on Sunday morning. The taxi driver was injured.

Russ Jackson, the head of counterterrorism policing for northwest England, said Al Swealmeen had rented a property in the city in April and been making "relevant purchases" for a device at least since then.

Jackson said investigators so far had not found any other people "of concern."

Detectives are also piecing together details of Al Swealmeen's life and say a relative told them he was born in Iraq. He applied for asylum in Britain in 2014, but was rejected, authorities said. It's unclear what his legal status was at the time of the bombing.
