A strictly Orthodox man has been found guilty of kidnapping and raping his ex-wife .
The man showed no emotion as he was convicted of one count of kidnap, two counts of rape and one count of false imprisonment.
Sentencing will take place on Monday.
The jury at Snaresbrook Crown Court reached their verdict after hearing how the man had knocked out his victim with a gas spray, and taken her to what she described as a dungeon inside a warehouse.
