The Appeal Court turned down a request for TV actor Thanapat "Toy Toy" Chanakulpisan to be released on bail, confirming the Min Buri Court's decision yesterday.
Police said Thanapat, 21, had confessed to killing his girlfriend Chatsaran Suwannakit, 25, at a townhouse in Bangkok's Khlong Sam Wa on Friday.
According to police, the actor said he and Chatsaran quarrelled over his work and she told him to pack up and leave the house.
He said she went to the kitchen and came back with a knife. They fought over the possession of the knife and he stabbed her in a blind rage, killing her on the spot.
After the incident, he waited and surrendered when police arrived.
When Thanapat was taken to the Min Buri Court on Saturday, his lawyer filed for his release on bail while police asked the court to reject the request.
The court denied the request on the ground that the crime carries severe penalties and the suspect could take flight if released.
The lawyer lodged a request with the Appeal Court which dismissed the request, saying the lower court's decision was correct. Thanapat is being detained at the Min Buri Remand Prison. The first 12-day detention period is from Aug 7-18.
