The man arrested on suspicion of pushing a woman in front of a bus on Putney Bridge says he was in the US at the time.
Lawyers for 50-year-old Eric Bellquist, who was arrested yesterday (August 10), say there is "irrefutable proof" that he was on the other side of the Altantic when the incident took place on May 5.
Duncan Lewis solicitors said in a statement: "Our client has been wrongly implicated in this matter; he categorically denies being the individual concerned and has irrefutable proof that he was in the United States at the time of the incident.
"Consequently we expect a swift resolution to this wholly untrue allegation."
A jogger running across the bridge in south-west London barged into a 33-year-old woman as she walked the other way, sending her flying into the path of the bus, which swerved and missed her head by inches.
The incident came to national attention this week when CCTV footage was released by police, in the hope of catching the man responsible.
Police have praised the public for their "good response", with several newspapers covering the story.
