A WEST Ipswich resident, who lived next door to the men accused of making a bomb which maimed a young boy, said explosions had been happening at his neighbour's property for 18 months.
Mark Anthony Tear, 39, and Glen Charles Dell, 44, have pleaded not guilty to charges stemming from an incident in May, 2013, in which a 15-year-old had his hand ripped apart by a golf-ball bomb.
It has been alleged a teenage friend of the victim found the home-made bomb in a street in Leichhardt. The victim was playing with the device when it suddenly detonated. Tear and Dell both face grievous bodily harm charges, with Dell further charged with carrying dangerous goods on a vehicle.
As the trial continued yesterday, truck driver Ashley Porter, who had been a neighbour to Tear and Dell, said explosions had been "going off" around the neighbourhood since Tear moved into the house.
Mr Porter said the explosions had been happening "periodically" for about 18 months.
Tear and Dell had their property searched following an explosion at their house on July, 2013, in which Tear suffered injuries to his hands and groin.
Officers scoured the Clay St property and uncovered a stockpile of an explosive bomb-making chemical called Triacetone-Triperoxide, also known as TATP. Crown prosecutor Noel Needham has alleged the substance inside the golf ball bomb which injured the teenager was also TATP.
The same explosive was also found in a home-made bomb which was planted at the West Ipswich Bunnings Warehouse construction site on May 15, 2013.
Bomb Squad Sen Const Craig Coutts said TATP was relatively simple to make and looked like a white, crystalline powder.
"A couple of grains of this material will detonate given the right stimulus and that could be something as simple as striking it with a hammer," he said.
The trial continues.
