A policeman died Saturday of wounds sustained in a bombing near East Eker village, south of Bahrain's capital Manama, the country's interior ministry announced.
The ministry said the policeman was on duty when the explosion occurred Friday night, according to Xinhua.
Chief of Public Security Maj. Gen. Tariq Al Hassan said the policeman, Mahmood Fareed, died in the early hours of Saturday after he was transferred to a hospital.
An investigation has been launched to identify and arrest the suspects.
According to official figures, 13 police officers have been killed and more than 2,600 people have been injured since Bahrain's majority Shias led large-scale protests against the Sunni monarchy in 2011.
