A doctor who claimed to have been kicked by a Swiss man while she was sitting on the steps near his property on Phuket's Yamu Beach in February has said she will appeal his acquittal on assault charges.

Dr Thandao Chandam, 26, said on Thursday that she was disappointed by the court’s ruling.

Thanking the public for the support she received during the case, she said she would continue to fight for justice.

Urs “David” Fehr, 45, was accused of kicking Dr Thandao in the back while she and a friend were sitting on the beachfront steps near his rented villa on Feb 24.

The man had allegedly accused the doctor of trespassing on his rented property.

The steps leading down to the beach were not part of the property and had been built illegally. They were later demolished.

The alleged kick was captured on a phone video, leading to a public outcry and calls for Mr Fehr’s deportation.

Mr Fehr was subsequently charged with assault.

However, the court on Tuesday acquitted Mr Fehr, as the doctor produced no clear evidence proving assault. 

Mr Fehr has always said that he slipped on the steps and his leg came up in the air, which gave the appearance on the video that he was delivering a kick.
