Missing man in York, red jacket, blonde hair

I lost my brother, Amir Hassan, 28, yesterday around 3pm in York. He's tall, about 6 ft 2 in, with short blonde hair and a light beard, and he was wearing a bright red puffer jacket, dark jeans, and a blue backpack with a neon yellow rain cover. The last sighting was near the York Minster steps, with a quick look around The Shambles Market before he disappeared into the crowd. He has a small anchor tattoo on his left wrist and a faint scar above his right eyebrow. I'm really worried—he doesn't have his phone on him, and I just want him back safe. If you see him, you can message me here in the app; I can share recent photos and more details.
