Dilara was on her lunch break in the London store where she works when a tall man walked up to her and said: “I swear red hair means you’ve just been heartbroken.”

The man continued the conversation as they both got in a lift, and he asked Dilara for her phone number.

What Dilara did not realise was that the man was secretly filming her on his smart glasses - which look like normal eyewear but have a tiny camera which can record video.

The footage was then posted to TikTok, where it received 1.3m views. “I just wanted to cry,” Dilara, 21, told the BBC.

The man who filmed her, it turned out, had posted dozens of secretly filmed videos to TikTok, giving men tips on how to approach women.

Dilara also found out that her phone number was visible in the video. She then faced a wave of messages and calls.
