SA men caught with home-made bomb

The discovery of a home-made bomb in a car near Adelaide has helped police uncover a drug lab.

Two 40-year-olds and a 34-year-old were arrested when police found the device during a traffic stop in Murray Bridge last week.

Methamphetamine equipment was later uncovered during a search of the car owner's home.

A 43-year-old man will appear in the Murray Bridge Magistrates Court on July 11 charged with drug manufacturing.

The men charged over the bomb will appear in court on May 4.
