More than 110,000 people have now watched an amateur video (above) of a member of Iran’s security forces beating up a young man on a Tehran street on February 11, the 31st anniversary of the Iranian Revolution.

RFE/RL correspondent Golnaz Esfandiari spoke with the young Iranian man who posted the video on YouTube. Twenty-three-year old Sam, who lives in Tehran, says he received the video clip via Bluetooth on February 11 and immediately decided to upload it on YouTube for the world to see.

RFE/RL: You didn’t videotape the scene yourself, but it was sent to you. Can you please explain how and by whom?

Sam: There were tight security measures on February 11, and if anyone looked a bit different, [security forces] would stop that person and ask him whether he or she was filming. They would also check people’s cell phones. There were many Basij militia members everywhere. When I went to Azadi Street, I saw lots of people, but there weren’t any [protests]. Basij and police cars were there, too. They stopped me and checked my mobile phone.

On the way back, someone sent me the video clip [of the beating] via Bluetooth. As you can see from the clip, the person who videotaped the scene was not on the street. It looks like it was done from a building. It’s short, though. I think because that person did not want to be identified.
