POLICE responded to two separate incidents involving explosive devices on a busy day in January this year.
On Thursday 15 January police were called to an address along Boobyalla Street in Doveton around 1am.
Two 15-year-old twins heard a loud explosion and went outside to find a glass bottle and wires in their mail box.
The soda bomb device was detonated ahead of another, similar report that day.
At around 5.30pm in Nerrena Rise in Cranbourne West, fireworks were discovered in a plastic milk bottle which luckily did not explode.
Minor damage was caused to a car in the driveway where the device was found.
Police said this is not unusual activity for this time of year and said they have had to call on the Bomb Squad to detonate these devices in the past.
They also encouraged people who find these devices to stay away and call triple zero as soon as possible.
