The victim, 35, sustained several wounds to her body.

Police will seek an arrest warrant for an unnamed 40-year-old male suspect caught on security cameras at the scene.

Huai Khwang Police deputy superintendent Lt-Colonel Supachai Harnkhamkla inspected the scene of the murder after receiving a report on the attack at about 12.30pm.

A security camera did not capture the attack and police suspect the killer turned the camera upwards before carrying out the attack.

Metropolitan Police Bureau acting chief Lt-General Sanit Mahathavorn said police believed the attack was not related to a robbery because nothing was stolen from the victim.

“We are investigating further. It’s very likely a personal conflict,” he said.

An informed source said police would seek an arrest warrant for the suspect.
