TUCSON, AZ (Tucson News Now)- Crews are still working to remove a hive on Tucson's northwest side where at least a dozen people were reportedly stung and two were sent to the hospital. 

The initial plan was to try to save and relocate the estimated 50,000 killer bees at a home in the 5000 block of West Blackbird Drive near West Linda Vista Boulevard and North Bald Eagle Avenue.

"Before we even got a chance to open the hive, they mounted a full-scale bee attack," said Greg Denker with American Bee Control. "The veil I was wearing was totally covered with bees. (I was) unable to see."

Experts call this one of the most aggressive swarms they've ever seen. Denker says it's the worst one he's seen, and he's been working in this business since 1968.

"This particular colony, on a scale of one to five, this one is a five," Denker said. "Highly aggressive (and) perfectly willing to sting by the thousands."

McCain's town hall is making up for one he canceled a few weeks ago.  McCain abruptly canceled his town hall at BASIS School in Oro Valley at the end of March. 

No reason was given for the cancellation.
