On Thursday, London's Metropolitan Police announced on Facebook that a "man was arrested on suspicion of causing grievous bodily harm following police enquiries at an address in the Chelsea area on the morning of Thursday, 10 August". The private-equity specialist was out of the country when the assault occurred, his lawyer said.
A millionaire banker arrested over the "Putney Bridge Pusher" video has been eliminated from the police inquiry after he proved he was in the United States of America at the time.
Seconds later, a bus is seen swerving out of the way, and narrowly missing the woman, who suffered minor injuries.
A rather grim video of a male runner pushing a woman into traffic in south-west London spread like wildfire over social media earlier this week.
Mr Bellquist, a top boss at the Wagamama and Byron restaurant chains, says he has "irrefutable proof" he was in the USA at the time of the incident, which took place at 7.40am on May 5.
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.
According to CBS News, the bus stopped and passengers came to the woman's aid.
Police described the jogger as a white man in his 30s with brown eyes and short brown hair.
He was wearing a light grey t-shirt and dark blue shorts.
Officers are continuing to appeal for information and asked anyone who knows who he is to get in touch.
Police say the victim saw the man crossing back over the bridge and tried to stop him, but he kept jogging.
