Man arrested after shots fired, gun found

A man has been arrested for drug offences after gunshots were fired in western Adelaide and a handgun was found in the street.

Police were called to a townhouse complex in Seaton, just before 10pm on Tuesday, after reports of gunshots.

Officers found a bullet hole in an iron fence at the end of the driveway and a number of spent bullet casings.

A police dog also found a handgun in a nearby street, which is being forensically examined.

Investigators then attended another Seaton home and found a stash of drugs, believed to be steroids, and arrested a 31-year-old Seaton man.

He is charged with trafficking a controlled substance and remanded to appear at Port Adelaide Magistrates Court on Wednesday.
