Mr Ashton, a 22-year-old from Purley, south London, is said to have been killed after getting caught in the crossfire between rival gangs, as he danced with friends at a beach bar on the paradise island of Koh Phangan.
The island's police chief police said a 26-year-old Thai man had been arrested and a gun confiscated.
He has been identified as Ekkapan Kaewkla, or Lae Kaewkla and is expected to be charged with manslaughter.
Handcuffed and squinting the suspect can be seen pointing on the picturesque beach, as police observe.

Devastated friends and family of Stephen Ashton have paid tribute to the"amazing, funny" 22-year-old.
In a statement issued by the Foreign Office on behalf of the family, they said: "As a family we are completely devastated by the loss of Stephen from our lives.
"He has been taken away from us in such cruel and tragic circumstances in which he was an innocent bystander simply enjoying New Year celebrations.
“We are comforted in the thought that he was having a fantastic time with friends after such a difficult period following the loss of his much loved dad who passed away from a brain tumour in 2011 and the loss of his granddad a few months earlier.
“We were all so proud of him; he was a much loved son, brother, grandson and nephew.
"He will be truly missed by his family but also by the many friends he made during his life.
"We cannot comprehend how someone can carry out such a reckless act, giving such little value to human life.
“We ask that our privacy be respected to allow us to grieve.”
Mr Ashton had posted pictures on his Facebook page showing him enjoying his holiday in Thailand.
