Circus performer Nik Wallenda has walked across a high-wire over a busy road without a safety harness.

The six-time Guinness world record holder climbed 200ft (61m) into the air for the daring stunt in his hometown of Sarasota, Florida.

It took Wallenda about 15 minutes to complete his balancing act from Bayfront Park to the Marina Tower building.
