"SPI has carried out a few investigations at Bukit Batok Park, where a female jogger died from an attack.
During the first investigation, we recorded electro voice phenomenon (EVP) at the spot where the victim was attacked after midnight. We heard unexplained music and recorded a man's voice.
We went back some years later to investigate again. We had a volunteer that we briefed before setting up the gadgets - like an EMF mter, night vision camera, motion sensors, and an EVP recorder - around her before retreating to watch over her at a distance. Suddenly, the gadgets powered down on their own and almost all the batteries had to be replaced, even though we had fully charged them beforehand.
The volunteer then told us via the walkie talkie that she heard something. After which the motion sensor alarm sounded so two of our members ran over to where she was. One of them shouted while the other took off after something! When we asked them afterwards, they said they both saw a white figure pass by swiftly. When we studied the video footage from the incident, it actually captured the same white figure passing behind the volunteer, while the EVP recording captured a low male voice sighing."
