A man who was arrested this year on suspicion of shoving a woman in front of a moving bus in London in 2017 was found dead at his home on Tuesday, the police said.

The Metropolitan Police said its officers had been called to an address in the West London neighborhood of Chiswick around 7 p.m. Tuesday after a 44-year-old man was found unresponsive at a house there. He was later pronounced dead, the police said, adding that the death was “unexpected but is not believed to be suspicious.”

The police confirmed in a statement on Thursday that the man was Nicholas Brandram, who was arrested in June in connection with the 2017 attack and had been released while the investigation progressed. He had not been charged in the case, but the police said their investigation into the pushing episode would continue.

According to the BBC, Mr. Brandram’s family said in a statement on Thursday that he “took his own life after months of immense pressure caused by a Metropolitan Police investigation” and that there was “no credible evidence” linking him to the incident.

Dan Knowles, a chief superintendent with the Metropolitan Police, said in the statement on Thursday: “Our thoughts are with Mr. Brandram’s family and friends at this deeply distressing time. We recognize the significant impact his death will have on those who knew and loved him. We also understand the strain that being subject to a police investigation can place on individuals and their families.”

In May 2017, a male jogger, apparently unprovoked, shoved a 33-year-old woman in front of a bus as it was traveling along Putney Bridge in West London.

The woman fell backward and narrowly avoided serious injury when the bus driver abruptly swerved into the next lane, according to CCTV footage of the crime, which shocked Britain.

Surveillance cameras captured the jogger running on the other side of the bridge about 15 minutes later. He ignored the victim when she confronted him, video footage showed.

“The victim was put in extreme danger when she was knocked into the road,” Sgt. Mat Knowles, the investigating officer from the Putney Safer Neighborhoods Team, said in a statement after the attack. “It was only due to the superb quick reactions of the bus driver that she was not hit by the vehicle.”

At the time, the suspect, who came to be identified in the British news as the “Putney pusher,” was described only as a white man in his early to mid-30s, with short brown hair and brown eyes. The police looked into leads involving more than 50 people but said a year later that the trail had gone cold.

In June, nine years after the attack, the police said that they had arrested a 44-year-old man on suspicion of grievous bodily harm in relation to the incident. The police confirmed on Thursday that they arrested Mr. Brandram in June after someone contacted officers with new information about the case.

Mr. Brandram was released last week, the police said, and was not subject to any bail conditions.

Mr. Brandram was a former soldier in the British Army who more recently worked in private banking, according to the BBC.
