BBC Leeds Protest 4 April - Riot vans... arrests?

Well, I was walking into work this morning, about 8:30, and a group of no more than 4 people were protesting outside the bbc in leeds, on woodhouse lane between the two universities - one lane of the road was blocked off, but it wasn't a sit-down. There were 10 people, definately no more than that, on the pavement, obviously wary of arrest. I couldn't join in, I work helping disabled people, and I don't think it right to skip work when they are in need of assistance - I'm just doing some paperwork now, and thought I'd post this here as it was only 40 minutes ago. So, as I was passing, the two cop cars already at the small protest (the policemen from these cars were pretty much just hanging around and directing traffic into the single open lane - i think they must have been there a short time already. Anyway, just as I had passed, 6 riot vans arrived at breakneck pace and the policemen, some in riot gear, streamed out. Another van was heading in the direction a few minutes later when I was further down the road. I wish I could have stayed to join the protest, does anyone know what happened next? Any plans for the rest of the day?
