The man is thought to Tarik Jadaoun (dubbed Abou Hamza Al-Belgiki). He voiced the threats in a Skype conversation. "You will never be safe. Our brothers are hiding everywhere and they are waiting for orders to attack."
The man is also ready to return to Belgium himself. "We are not afraid of the police and intelligence services. We know how to cross the borders without being noticed. I have a plan in mind. If I leave, they won't be able to find me and they don't know who I am."
Intimidation, or real threats? The man is being monitored by Belgian detectives. Investigators confirm they have been following the man for a long time already and that they are taking the threats seriously.
