Metropolitan Police Division 4 has established an investigation panel into the death of a woman who fatally fell from an apartment building in the Chokchai Si area.

Ekkaphob Luangprasert, an adviser to the Interior Minister, on Monday accompanied the student's father, who was identified only as Somchai, to track the case investigation process with Chokchai Police Station superintendent Pol Col Sretthaphan Srisakorn.

Mr Somchai's daughter, a 27-year-old doctorate student identified only as Arphaporn, fell from the balcony of her sixth-floor apartment on Sunday. She was frightened by a drunk man who banged on the door of her room at 4am, prompting her to climb out of a window to escape, before falling to her death.

The suspect told investigators that an apartment cleaner had wrongfully told him about the owner of a motorcycle parked in a parking space reserved for him that night.

According to Pol Col Sretthaphan, the suspect is now being accused of illegally entering a residence, frightening others and making a commotion.

In addition to work done by the investigation panel, police will review CCTV footage and speak with more witnesses.

Pol Col Sretthaphan added that further investigation is needed to determine if the apartment manager's alleged attempt to assist the suspect in leaving the scene at the time was a criminal act.

The family of the dead woman is expected to receive more than 100,000 baht in compensation as per the law, said Pol Col Sretthaphan.
