Two brothers who allegedly torched a shooting club in Halkida after having their membership revoked for aggressive behavior have been detained, police said. The pair, aged 35 and 37, were caught early yesterday after an arson attack on the Evia Shooting Club that resulted in major damage but no injuries. According to police, the brothers had been dressed in masks and military uniforms and had been armed with crowbars. It is believed that one of the two kept watch while the second broke into the club and planted a homemade explosive device, made of gas canisters, which caused serious damage when it detonated. Police believe the pair planned the attack as revenge for the club president’s decision to expel them for «antisocial and problematic behavior.» A search of the siblings’ home unearthed four hand grenades and three hunting rifles, with corresponding licenses, as well as two unlicensed shotguns.
