Due to the serious injuries the foreign victim had passed away before the arrival of the medical team, SRCA spokesman added.
Foreign workers are facing beatings, torture, rape, abuse and death in Saudi Arabia.
Human rights groups have rapped Saudi Arabia over the condition of migrant workers in the kingdom and called on Riyadh to respect the rights of the migrant workers.
