TASMANIA police has decided not to take action against North Melbourne coach Brad Scott over an alleged clash with a security guard at Blundstone Arena in May.

A media release from Tasmanian police said the investigation was dropped based on legal advice.

"The complainant alleged that he was kicked in the back while sitting down and was left with redness and soreness," the statement read.

"The legal advice was that, based on the evidence available, there would have been little prospect of conviction."

The AFL believes the matter has been settled and preferred not to comment when contacted by AFL.com.au on Friday afternoon.

Scott denied the allegations when speaking to reporters in May.

"Things will come out in the wash up," Scott said.

"All I can say is, I absolutely welcome an investigation and look forward to putting the facts in the story."

The North coach is recovering from back surgery and has been on leave from the club since early June.

Scott has not coached since round 10 with Darren Crocker taking over as caretaker.

He is expected to be back in the coach's box in round 15.

The club hopes to have him back at Arden Street a week earlier, but he will not be able to fly to the Gold Coast for the Roos' clash with the Suns in round 14.
