41-year-old Eric Bellquist, a USA citizen, was questioned by police but denies any involvement.
The 41-year-old San Diego native was arrested Thursday after police believed he was the man captured on May 5 surveillance video pushing a woman toward a bus.
The video shows the 33-year-old woman, who was not identified, falling to the pavement and the bus quickly swerving to avoid her head.
Police have not named the person they arrested, but lawyers for a man named Eric Bellquist came forward on Friday to say his client had "irrefutable proof" that he was in the United States at the time.

On Friday, Eric Bellquist released a statement through his lawyers saying he had "irrefutable proof" he was in the U.S. at the time. The Guardian reports that he'd also worked for the now-defunct Lehman Brothers. It says he now represents Hutton Collins for the restaurant chains Byron Hamburgers and Wagamama, and had helmed the firm's investment in Caffè Nero. "It was only due to the superb quick reactions of the bus driver that she was not hit by the vehicle".
The jogger is described as a white man, aged early to mid 30s, with brown eyes and short brown hair.
Police said that 15 minutes later the jogger then returned to back across the bridge and ran straight past the victim, who tried unsuccessfully to speak with him.
Officers are continuing to appeal for any witnesses to the incident or anyone who recognises the jogger in the CCTV to get in touch.
