Police can't confirm link between homemade bombs
THE homemade bomb detonated at the new Bunnings Warehouse site in West Ipswich contained powder similar to that found in the explosive which left a Leichhardt teen severely injured.
A sample of the powder found in the Wednesday's device was taken for chemical analysis before the bomb squad performed a controlled detonation on Wednesday.
Ipswich Police Inspector Dave Preston said testing found the powder in both bombs was similar, but couldn't confirm if the substance came from the same batch of chemicals.
He said the powder was made from chemicals available for purchase.
Police have received little information from the public and are appealing for anyone with information to come forward.
Neighbours again reported hearing loud banging noises around the construction site on Wednesday night.
The bomb was tied to a fence, with a trip wire in place to set it off.
The bomb contained a party popper as a detonator.
But the party popper failed to ignite and this prevented a bigger explosion.
Last week 15-year-old Michael Boggan suffered horrific hand injuries after a golf ball he was holding exploded.
Safe City cameras did not pick up any trace of people leaving the construction site on Tuesday night.
Anyone with information can call Crime Stoppers on 1300 333 000.
