A man completes a terrifying 'tightrope' stunt over Moscow's main thoroughfare, Tverskaya Street, to the shock of onlookers.

The dizzying feat was completed on Sunday at roughly 9:00pm.

Everything was okay and the man survived the journey, said filmer Hatem Kinawy. But "the police took him directly after he reached the building," he added.

Kinawy said he believed it may have been a phone wire, as opposed to a tightrope set up specifically for the event.
