For several years now, Hossein Derakhshan has been at the forefront of Iran's burgeoning blogging scene. Better known as Hoder he's been writing about the country and its politics online since - and, from time to time, he's also contributed to the Guardian.

After living in Canada for some time, he recently headed back to Iran - where now, it seems, he's been arrested and accused of being an Israeli spy. Details remain unclear; the only report appears to be from Jahan News, but a summary here gives the flavour of that report:

According to Jahan News, which is close to Iran's Intelligence community, Hoessein Derakhshan, the Iranian blogger who visited Israel in 2007 from Canada, has been arrested in Tehran.

According to what the article says are "credible sources", Hossein has admitted to spying for Israel. His confessions are said to include some "intricate" points.

We know that Iran has been clamping down on internet use again recently, blocking millions of websites in its attempt to keep dissenting voices out of circulation.

Brian Whitaker's already over on Comment is Free, while the issue is also being picked up by Global Voices Online and on a dedicated Facebook group.

Let's hope for the best.
