Olympic flames doused in Shenzhen?

Earlier, in Ohio
via WikipediaUnknown protestors have attacked successfully the Olympic torch relay in the South Chinese city of Shenzhen, according to this report in the Asia Sentinel.

The protesters’ motives were unknown. As the unsuspecting crowd cheered Beijing’s Olympic success, an eyewitness heard one of the two men, both of them Chinese, say “mission accomplished” after the torch was put out. Chinese television, which was filming the progress of the torch, hurriedly cut away. Television presenters said the transmission was having technical problems. However, the eyewitness was able to film the disturbance and made it available to Asia Sentinel. The film is being prepared for publication and was to be put on the site later today.

The relay of the Olympic flames was stopped for about an hour, according to the report, then the flames was relit and continued. I was first warned through a twitter from Danwei, supporting twitter's usage as a journalistic tool. More will follow later today.

Update I: Danwei has been looking for more support of the story in the Asia Sentinial but has not find anything yet.
Update II: Here is another update from Shenzhen, but no mentioning of this incident.
Update III: An overwhelming lack of supporting evidence continues.
Update IV: Still no supporting footage and more eyewitness reports that suggest that this Asia Sentinel story is rather unlikely. I have seen now some pictures where it was extremely busy with supporters. Any action against the flame would have been suicidal.
