The man on the train caught on camera what appears to be an upskirt video of a female commuter has a “habit” of “leaving his handphone on the surface of his bag”, said an ex-teaching colleague.

In an email to Alvinology.com, the ex-colleague who prefers to be known as Ms Naidu said the man is a “very close friend” of hers and they were “ex-MOE colleagues”.

“I would like to speak out in hopes of justice for my Friend who’s being a victim of this accusation at the moment that is circulating online,” she added.

Alvinology.com understands that the man is David James Chua and he is 30 years old.

A Facebook video posted on Saturday (15 July) showed the man – dressed in a pink T-shirt and black shorts – using his mobile phone and then placing the phone, with the camera facing up, on top of his bag which could be seen left unzipped.

In the same video, he could be seen placing his bag – with his mobile phone still on top of his bag with the camera facing up – close to the legs of a woman standing behind him.

This happened in the train that was travelling between MacPherson and Paya Lebar stations on the Circle Line.

On Monday (17 July), Xinmin Primary School vice-principal Clement Lee confirmed that the man in the video is one of its teachers.

Mr Lee also added that the man is a “beginning teacher” who was posted to the school on 13 June 2016.

The teacher is currently placed on leave, he said.

A check on Xinmin Primary School’s website showed that one of its Physical Education (PE) teachers fits the profile of the man.

Ms Naidu, who knows Chua for five years, said he has a “habit” of “leaving his handphone on the surface of his bag at our home or when we are walking together in places where there are absolutely no people around.”

“It’s a “habit” not a perverted purposeful act like what the Internet and viral video claims of him,” she said.

She added that she has photos showing Chua “carrying the same bag and putting his stuff just on the surface of his bag”.

Ms Naidu also questioned the intention of the person who took the video.

“And if this was indeed an upskirt video by a pervert kind of situation, I don’t see how the person videoing my Friend could calmly sit down and continue to video without having the urge to alert anyone then and then,” she said.

The clip, which is slightly over two minutes long, showed the female commuter moving towards the center of the cabin to stand behind Chua.

The alleged upskirt incident took place in the last 10 seconds in the video.

On Chua, Ms Naidu said: “This person has a gem of a heart and will never commit anything like this. He deserves justice and the Internet has to stop spreading fake news just to get attention while ruining an innocent person’s life.”

“I’m ready to battle this out to prove his innocence as a Friend and a Singapore Citizen for the justice of anyone for that matter in being falsely defamed and having their entire life ruined overnight by this social media sites. This is cyber bullying when you read the contents and information fellow netizens are putting out there of this innocent party when even in the video it shows no evidence of having an intention to film upskirt,” she said.

Speaking to Alvinology.com, Ms Naidu said: “There is no glimpse in his characteristics to suggest that he is capable of doing such an act. I know that he is not guilty.”

Police confirmed that a report has been lodged and that investigations are ongoing. Chua has also been prominently featured and covered in various Singapore-based traditional and online publications.
