A funeral march in memory of Salah Abbas Habib, who was killed in protests during last weekend’s Bahrain Grand Prix, turned violent on Thursday.
Crowds attacked a police station in the capital Manama with petrol bombs, setting it alight and police responded with tear gas and stun-grenades.
Traffic was held up on a nearby motorway for an hour as clashes spilled into the surrounding areas.
Habib’s body was found on Friday after protests. Friends say it was riddled with bird shot and bore signs of torture.
