Saudi Arabian police have arrested a man in connection with the November 8 suicide bombing in Riyadh that killed 17 people, the Interior Ministry said.
The suicide bombing killed 17 people and wounded scores.
The bombing was preceded by warnings of a pending terrorist attack issued by the Australian, British and US embassies in Riyadh.
In May, Islamic suicide bombers attacked three compounds for foreigners in Riyadh, detonating vehicle bombs that killed 35 people including the nine assailants.
The attacks triggered a massive crackdown with security forces detaining about 600 suspects, of whom nearly 200 were soon released.
