Ipswich golf ball explosive A 50-year-old man has been charged after police found more explosive chemicals on a vacant Ipswich block next to a home that was rocked by a blast two weeks ago. Police cordoned off the area surrounding the vacant block on Darling Street on Wednesday evening after discovering a small quantity of an explosive chemical. The chemical was destroyed and the police cordon ended at 6pm. Police returned to the vacant block on Thursday morning, where they destroyed another suspicious object as a precaution. Detectives later charged a 50-year-old man with one count each of possessing explosive material, disposing of explosive material and supply of dangerous drugs. He is due to face Ipswich Magistrates Court on August 23. Last week officers carried out 14 controlled explosions at a nearby house on Clay Street, which was riddled with explosives. Two men who lived at the house allegedly stockpiled about two kilograms of volatile chemicals to make homemade bombs for fun. Another man, Glen Charles Dell, 43, is in custody, charged with weapons and explosives offences. The charges relate to the explosion, as well as an incident in May that maimed a teenager who picked up a golf ball bomb with explosive inside in a Leichhardt park. Police will allege that bomb was targeting a builder.
