WATCH: Fan Arrested for Crashing Stage at Taylor Swift Concert in San Diego

No Thanks
Ian McKellan is fine with not being on the Squad.

Don’t mess with Taylor Swift… or her security squad.

On Saturday — the same evening Taylor got “Complicated” with Avril Lavigne and became OMI’s “Cheerleader” — the 1989 World Tour in San Diego was also the site of an arrest for one particular fan.

Sources have confirmed to TMZ that Christian Ewing, 26, “charged” the stage during Taylor’s performance of “Style.” As you can see in the video, below, the fan was nowhere close to the singer, who was already down her 1989 runway. Still, a stranger on the stage means danger, which prompted four security guards to contain the guy. One guard left the debacle with a broken rib, according to TMZ.

Ewing, whose bail is at a cool $35,000, has since been booked for felony and misdemeanor battery and obstruction.

The 1989 World Tour will take a small break before heading to Salt Lake City on Friday (Sept. 4).
