Detectives from the Arson and Explosives Squad have charged a teenage boy following an alleged explosion in Carrum Downs in August.
The 17-year-old from Carrum Downs has been changed with six counts of explosive related offences regarding the incident which is alleged to have occurred at a reserve on Hillview Drive about 5pm on 28 August.
He has been bailed to appear at a Children's court at a later date.
A 16-year-old Seaford girl who was also arrested this morning following a number of search warrants at residential properties in Carrum Downs and Seaford, has been released pending further enquiries.

Two occupants who were home at the time, were not physically injured.
