Letterboxes on bomber hit-list
A SPATE of what has been described as "unexplained explosions" - some of them involving the destruction of letterboxes - has prompted an investigation.
Police over the past week have been called to seven incidents where Ipswich residents have complained of hearing a loud explosion.
Of those incidents, three were confirmed to have involved the use of a small explosive made from party sparklers to destroy a letterbox.
These occurred at Leichhardt and Basin Pocket on Thursday night and Tivoli on June 17.
Ipswich district crime manager Senior Sergeant Greg Smith said it was possible the incidents were linked to the same offenders and police were compelled to act out of concerns for the safety of residents.
"It appears that aluminium foil has been used to make what is commonly known as a sparkler bomb," he said.
"These things can be pretty nasty. Apart from the initial explosion there is also the risk that shrapnel can strike anyone standing nearby.
"Realistically, these things can kill a person," he said.
The Queensland Times has reported on several recent incidents where people have been gravely injured by shrapnel from sparkler bombs.
Snr Sgt Smith said anyone who sees anything suspicious in their letterbox or elsewhere should contact the police or fire service and stay well clear.
In the latest instance, some witnesses reported seeing a small sedan driving away before the explosion. However, the make and model given to police was not consistent enough to narrow the search down.
