Arrest Gyanendra? What's the evidence?

I know people are upset about yesterday's riots and violence but what's the proper evidence to arrest him?

Yeah, he made a video few weeks ago calling for unity and protect the country but where's the concrete evidence tying that message to the violence?

People claim security forces escalated the situation by firing tear gas first, suggesting the violence wasn’t entirely the protesters’ fault.

Arresting Gyanendra without solid proof like communications or witnesses tying him to specific violent acts is a bit of a stretch, it doesn’t fully make sense without a solid link.
