Campbell Brown's Gold Coast Suns leadership position is on shaky ground after being detained by Thai police with three AFL team-mates following a night of post-season revelry.

The fledgling AFL club will investigate an alleged fight between Suns players, an off-duty policeman and an Australian tourist on the island of Ko Phangan where they attended a dusk-to-dawn beach party.

Pictures of an unclothed and handcuffed Brown, Gold Coast's deputy vice-captain, embarrassed the Suns on Thursday.

But a club spokesman has suggested the former Hawthorn premiership defender had attempted to assist teenager Maverick Weller who had been provoked by a tourist.

Fellow rookies Joel Wilkinson and Jacob Gillbee have also been named as players taken into custody by police, but not charged, after jumping into the fray.

Brown, 28, and the young trio return to the Gold Coast on the weekend when they will immediately be questioned by Suns officials.

Chief executive Travis Auld would not pre-empt any disciplinary action on Thursday but stressed the club viewed player misbehaviour "very seriously".

"We will take the opportunity to meet with the players to determine all the facts," Auld said.

"Once we're in possession of all the facts we'll be in a position to make a decision regarding the next steps.

"As the club has demonstrated over the past three years we take player behaviour very seriously."

Auld, football manager Marcus Ashcroft and senior coach Guy McKenna will interview the quartet and handle the investigation.

Brown played 14 games for the Suns in their inaugural season but also let the wooden-spooners down on the field when suspended for four matches for two reckless acts in just their second match against the Western Bulldogs.

Asked whether he was disappointed to see photographs of his deputy vice-captain in police custody, Auld admitted it was not a good look for the club.

"Having one of our players in the newspaper as it's been shown is not the position we want them to be in," he said.

"But once again we're not going to judge our players or the incident until we understand exactly what took place."

Tasmanian recruit Weller played 15 games in his debut season.

The 19-year-old Tweeted on September 10 he was, "Off to Thailand with the boys!!", and two days later, he wrote: "koh phangan fullmoonparty."
