Eric Bellquist, an American investment banker and a partner at a private equity firm in London, has been arrested in connection with a frightening attack that saw a woman shoved into the path of an oncoming bus.
Closed circuit TV footage showed the male runner knocking a 33-year-old woman head-first in front of a bus which just managed to swerve out of her way.
But, 48 hours after news of the arrest was announced, the Met police said they had released Bellquist and eliminated him from the investigation.
His lawyers later released a statement saying he wasn't involved and could prove he was in the United States at the time of the May 5 incident.
After the May 5 incident, the bus stopped, while passengers climbed off to help the woman. The partner who works for Hutton Collins Partners denies that he had anything to do with it. He previously worked for Lehman Brothers and is a graduate of the University of Colorado Boulder.
Police described the jogger as a white man, aged early to mid 30s, with brown eyes and short brown hair, wearing a light grey t-shirt and dark blue shorts.
The woman was put in "extreme" danger and only avoided a passing double-decker bus because of the quick reactions of its driver, police said.
Officers continue to appeal for any witnesses to the incident.
Metropolitan Police say the jogger came back across the bridge 15 minutes later; the victim tried to speak to him but he did not acknowledge her and carried on jogging.
