TransLink's police force is looking for the victim and the witness of an upskirt photographer to come forward and assist in its investigation.

The incident in question happened at the North Vancouver SeaBus terminal at around 11 a.m. PT on Sept. 13.

In a press release, Transit Police said that a SeaBus rider spotted a man pretending to tie his shoes, while actually taking photographs up the skirts of women.

A SeaBus attendant, alerted by the witness, saw the man apparently taking an upskirt photo of a young woman in a red dress. The attendant called transit police and told the woman, who appeared to be in her 20s, what happened. She then got on a SeaBus to Vancouver.

Transit Police seized the cell phone of the 36-year-old suspect, and he was later released.

"Officers found that both the victim and the witness had left the area without providing contact information. Investigators would very much like to speak to both of these people and ask that they call 604-515-8300 as soon as possible," TransLink said in a written statement.

Translink also said any other victims or witnesses of similar harassing or disturbing behaviour should call Transit Police to report it.
