Man found on SA roof arrested

A man who refused to come down from the roof of a Port Adelaide shop has been arrested after a brief stand-off with police.

The 25-year-old was spotted on the roof of the Semaphore Road business at 5.45am on Monday and arrested after being found with a folding knife and spray cans.

He was charged with a number of offence, including breach of bail, and will face court later on Monday.
