Police have closed an investigation into a jogger who knocked a woman pedestrian into the path of a bus.

The 33-year-old victim was lucky to escape serious injury after the bus driver swerved to avoid her on Putney Bridge in south-west London.

The Metropolitan Police launched a hunt for the jogger last August, three months after the incident, and looked at more than 50 people as part of their investigation.

Police have now said all lines of inquiry have now been “exhausted”.

The victim, who suffered minor injuries, was ignored by the runner some 15 minutes later as he ran past her on the bridge going the other way after the incident on the morning of May 5.

The bus driver, Oliver Salbris, has been labelled a hero for his quick actions in swerving to avoid the woman.

He told the Sunday Times in September he thought he was going to hit her.

“If I hadn’t swerved, I would have smashed her head,” he said.

“It was reflex. The consequences would have been terrible for her – and for me.”

He said the jogger “looked like he was doing it on purpose”.

“He needs to be caught and to explain himself. He needs to be prosecuted,” Mr Salbris added.

A Metropolitan Police spokesman said: “Officers looked at over 50 people of interest during the course of the investigation; all of them were researched, reviewed and eventually eliminated.

“The matter was investigated fully with all reasonable lines of inquiry completed.

“As a suspect has not been identified and as all lines of inquiry have now been exhausted, the investigation has been closed. Should any new information come to light, this will be explored.”
