At least 25 people were detained in the Polish town of Elk on Sunday after they smashed up a kebab diner and clashed with police, throwing firecrackers and stones. Up to 300 people took part in a rally after a Pole was allegedly killed by men of Arab descent.
City authorities in Elk, a city of 60,000 in northeast Poland, have requested extra police forces to be dispatched to secure public order after mass disturbances rocked its streets on Sunday. A few hundred locals gathered in front of the Prince Kebab diner to light up candles in a vigil for a 21-year-old Daniel, a local resident, who is said to have been stabbed to death in a brawl involving foreign employees of the café on Saturday night.

Shortly after the gathering turned violent, some people started to hurl stones and firecrackers at the building, smash its windows, broke into the premises and destroyed the cafe’s property. As the police tried to calm down the protesters, they turned on officers, showering police cars with firecrackers, bottles and stones.
