Masa Amini. Now that is a name that I'm sure many of you will be familiar with, but if not,

she was a 22-year-old Kurdish-Iranian woman. She was visiting Iran's capital Tehran with her family.

It was there she encountered the Morality Police, who arrested her for the crime

while of not wearing her headscarf properly.

Three days later, still in custody, she was dead.

but I hope that by the end of the episode you'll remember.

Motileb Saeed Piru.

He was murdered in broad daylight in October in the north of the country.

investigation by Sky's data and forensics unit casts, well, significant doubt over that version of

events. It also sheds light on the tactics used by the Iranian regime to try and suppress the

dissent, the uprising, taking place in the Islamic Republic of Iran.

Today, we bring you the story behind that investigation. I'm Neil Patterson, and you're listening

And as for the regime and its control over the internet, well, it's almost complete.

They can switch it on and off as they like.
