Bro, it doesn't matter as his name is listed in wanted list. Whatever he was Bahraini or Saudi, these people are working for foreign intelligences to spread terrorism and mess over the country.
These terrorist cells were existed to create a strong party inside the country so they can use it to push on the government like Hezbola in Lebanon, Houthis in Yemen ...etc. But they will never get that and who involve himself in such attempts will be sent to hell.
Few days ago, a cell of 30 terrorists were arrested and accused of spying for Iran.
However, I don't feel worried about the situations. With King Salman we may see their heads chopped off soon.
