COPENHAGEN (Reuters) - On Valentine's Day, two weeks after his release from prison, Omar Abdel Hamid El-Hussein walked up to a Copenhagen cafe hosting a debate on freedom of speech and sprayed it with bullets.

As a manhunt began, the 22-year-old went to ground. Nine hours later he launched a second assault, this time on a synagogue. Police eventually shot him dead, ending a rampage that left Danish filmmaker Finn Noergaard and security guard Dan Uzan dead, and six people wounded.
