"British police were searching for a "suicide vest" laced with dangerous chemicals after a raid of the alleged bomb factory yielded two suspects but no vest.
In London, a 23-year-old postal worker was being questioned in a hospital and his 20-year-old younger brother was being held in a police station after their parents' home was raided Saturday morning, The Times of London said.
Police think the vest has been made and will be set off at a busy bus or train station, or in a crowd watching a World Cup game in a local pub, The Times said.
Law enforcement officers wearing oxygen masks and chemical protection gear raided the London house after receiving a tip that the vest had been assembled.
The postal worker was shot in his shoulder.
The Times reports Scotland Yard thinks the vest was put together in the house."
