A HOMEMADE bomb planted at the Bunnings construction site in Ipswich West could be related to a feud between protesters against the development and the home hardware giant.
The device was detonated by the police bomb squad after it was partially detonated when a construction worker triggered a tripwire connected to it at 6.30am yesterday.
The device was tied to a fence at the Darling St West site entrance.
Police said the device contained a powder, but it contained no shrapnel. It was poorly made and party poppers had been used, unsuccessfully, to detonate what would have been a larger explosion.
The initial explosion was heard blocks from the site, but construction worker Roger Moore was not injured in the incident.
Ipswich police swiftly blocked off the street and awaited the arrival of the bomb squad.
The squad operated a robot by remote control to cut the device from the fence and then x-ray it.
An officer wearing a full bomb suit then approached the device in scenes similar to the aftermath of the tragic explosion which left Leichhardt teen Michael Boggan with severe hand injuries on Friday.
The bomb squad performed a controlled detonation of the device at noon.
The entrance is regularly used by up to 30 trucks a day.
However, the entrance was not used on Tuesday because of the wet weather.
Inspector Dave Preston, of Ipswich police, said the powder found in the device had been taken for chemical analysis.
Insp Preston said the developers had received threats from people unhappy with the building project.
"The company have told us they have received some verbal threats. They have been about ... the building going on there," he said.
Insp Preston said machinery had also been damaged on the site. Neighbours had heard loud bangs earlier this week and a Bunnings sign was reportedly set on fire over the weekend.
A Bunnings representative said the incident was a matter for the construction contractor and the police.
"We are working closely with both parties," the representative said.
The halt in construction is believed to have cost up to $100,000.
Mr Moore said he arrived for work and went to open the gate as usual when he spotted the fishing line.
"I pulled it to get it off the road and that's when it went off," he said. "There was a loud bang but not enough to do any damage. I was thinking what's going on? Is there any more?"
Neighbour Colin James said he had heard similar loud bangs once a day for the past week.
He said yesterday's incident shook his house.
"There were a couple of cracks and we have been getting them for the last week or so, and I don't know where they were coming from," he said.
