Police are seeking an arrest warrant for a man charged with clubbing his construction firm owner girlfriend to death at a hotel in Bangkok before fleeing, possibly to Cambodia.
Chokechai police have gathered evidence to present to court in seeking warrant for the arrest of Atsaya Chaipa, 33, said Metropolitan Police Bureau chief Pol Lt Gen Charnthep Saesawet.
Mr Atsaya is believed to have murdered Thitima Tangwibunphanit, 39, a businesswoman dealing in construction, real estate and transport, at a hotel on Pradit Manootham Road between July 26-27.
Her body was found in her hotel room on July 30 during a month-long stay at the property. Police mounted a search after Thitima's family reported her missing to Chokechai police on July 27.
According to Chokechai police chief Pol Col Surapol Khamchoo, Thitima was last seen on security camera footage entering the room with Mr Atsaya around 10.40pm on July 26. About three hours later, Mr Atsaya was captured on film leaving the room alone.
On the morning of July 27, Thitima's family said they called the woman on her mobile phone, which Mr Atsaya answered. He said Thitima could not talk at that time because she was busy making merit, according to Pol Col Surapol.
The family then sent the woman messages on the Line app, which had not been read, and Thitima did not return their calls. Pol Col Supol said the family regularly spoke with Thitima on the phone to discuss business matters.
On July 30, police traced her phone signal to the hotel on Pradit Manootham Road.
They said her skull had been cracked and a blood-stained baseball bat had been left near the body.
Police suspected Mr Atsaya, who is believed to have been romantically involved with the woman, and who may have had access to some of her assets, took off with Thitima's car, a Mercedes E-class sedan, in the early hours of July 27.
Police have pressed murder and theft charges against him.
Pol Col Supol said Mr Atsaya had driven the woman's car to the Thai-Cambodian border in Chanthaburi. He may have crossed the border and the police have alerted the Cambodian authorities.
Police also came across bank records showing Mr Atsaya had withdrawn hundreds of thousands of baht. However, it was unclear when the withdrawals were made and from whose account the money was taken.
Pol Col Supol said Thitima had lodged a complaint with Chokechai police against Mr Atsaya for assault. According to the complaint, the suspect had tried to strangle her.
Pol Maj Gen Theerapong Wongratthapitak, chief of the Metropolitan Police Division 4, said the suspect may have killed Thitima during a fight. He allegedly amassed gambling debts and borrowed a significant amount of money from her in the past.
Amnuay Wichaichote, 66, Thitima's father, said his daughter's firm was contracted to build a government-run housing project in the Lat Phrao-Wang Hin area.
