Two Murray Bridge men will face court on Thursday, September 17 after an investigation into car fires and property damage this month.
It is alleged two incendiary devices were thrown at a Croydon Park house just before 11pm on Saturday, September 12.
One of the devices exploded and damaged a window.
Then just before 12.30am on Monday, September 14, a car was set on fire at Milang.
The Holden Cruze was destroyed in the blaze.
About two hours later, two cars were set alight at Elizabeth North.
The Mitsubishi Magna sedan and Mercedes station wagon were extensively damaged.
On Thursday morning, September 17, two Murray Bridge men, who allegedly have links with outlaw motorcycle gangs, were arrested by Crime Gangs Task Force and Serious and Organised Crime Branch members.
The 29-year-old and the 20-year-old will face two counts of arson and one count of property damage when they appear in the Murray Bridge Magistrates Court the same day as their arrest.
