LONDON — The identity of a jogger in southwest London who pushed a woman into the path of a bus will most likely remain a mystery, as the police have said that all leads have been exhausted and that they are closing the investigation.

The inquiry began after the woman, 33, was sent tumbling into a bus lane on Putney Bridge on May 5, 2017, when the jogger shoved her off the sidewalk. She fell backward and hit her head on the pavement, narrowly escaping more serious injury after a bus driver saw her and swerved into the opposite lane.

The episode came to the attention of the public only months later, however, when the Metropolitan Police released surveillance video in August 2017, appealing to the public for information.

The jogger who pushed the woman immediately ran off, but surveillance cameras captured him roughly 15 minutes later running on the other side of the bridge, and ignoring the victim when she confronted him.
