THE "Putney Pusher" could finally be exposed by his body language, a leading expert claimed today - as cops probe new leads.

Sun Online can reveal how the bullish jogger's clenched fists and 'upright' running style show he had "pent-up anger" when he shoved a female pedestrian in front of a moving bus on Putney Bridge, west London.

He almost killed the woman in the sickening attack last May - but we can reveal today how he is likely to be an ordinary businessman who was "overcome by red mist".

Despite a huge public appeal and officers trawling hours of CCTV, it was revealed in June that police had slowed their manhunt after failing to identify him.

The investigation was shelved for a number of weeks before being dramatically reopened when fresh "leads" came to light towards the end of summer.

Now, in a fresh appeal for information, analysis commissioned by The Sun Online has shed new light on the character and potential motive of the Pusher.

Renowned body language guru Judi James says he may not be a typically aggressive or tempestuous person - and instead could have had a "red-mist flare-up".

Crucially, she insists that the public need to think again about who the Pusher may be - as he could be the friend, neighbour or relative who is normally calm and mild-mannered.

In her exclusive analysis, Mrs James says the Pusher's body language is indicative of a "perfectionist" who could be trying to stake a claim on his "territory".

She says: "It might be dangerous to imagine that this is a man already known for his temper or aggressive behaviour.

"To dismiss a partner, friend or family member who is normally calm and relatively passive could be disastrously naive.

"It it is important for people to look again.

"This terrifying behaviour could be totally in character — but it could also be an extreme version of a red mist flare-up.

"These can occur with road rage and other types of momentary outbursts that can be based on spatial ownership and desire for dominance.

"This man could believe that section of road is his by right — and believe he was justified in claiming it all."

Someone who normally jokes about the frustration of being blocked by pedestrians or stuck in traffic should also not be dismissed - as these jokes may hide a dark and deep-seated anger.

Mrs James adds: "This could be someone who often fumes to his family about pedestrians getting in his way but they might have believed he was joking."

His style of running also suggests the Pusher is an accomplished jogger who may be part of a club or gym, according to our expert.

She says: "The way he carries on running as though nothing has happened hints at a strong sense of self-belief.

"His style of running should throw up some clues if he ever runs with a friend or with a club.

"He's a stocky man but his movements look very rhythmical and fluid. His back is exceptionally straight and his head is held high.

"His arms are bent at a 45 degree angle and this kind of symmetry could suggest someone who is competitive or a bit of a perfectionist.

"Many runners lope slightly or carry their arms higher or flopping slightly lower."

And the anatomy of the push itself is indicative of someone with a chilling lack of empathy, our expert says.

"His hands do seem to be balled into fists which could suggest pent-up anger but could also be a sign of someone driven and competitive or even someone who works under pressure.
"The way he pushes the woman out of the way is interesting.

"There is no apparent sign of aggressive arousal that might suggest a big build-up.

"In terms of his running he barely misses a beat before or after.

"The push looks as though he places his hands high to her shoulders before almost flicking her away dismissively.

"This could be down to a sense of entitlement about the space."

A nationwide appeal for information was launched after the Metropolitan Police released blood-curdling footage of the push in August 2017.

But critics said the three-month gap between the incident and it being made public allowed time for the suspect to go into hiding.

The 33-year-old victim survived thanks to the fast reaction of hero bus driver Olivier Salbris, who managed to swerve the No 430 to miss the woman as she fell back into the road.

The front wheel of his 12-ton double decker came within inches of her head.

Olivier said the woman - who has chosen to remain anonymous - was screaming “why me?” after she was shoved into the path of the bus.

About 15 minutes after the incident, the jogger came back the other way across the bridge.

The victim tried to speak to him but he did not acknowledge her and carried on running towards the north side of the river.

Olivier, 45 — commended at the UK Bus Awards for his life-saving reactions — told the Sun: “I think the police have done all they can do, but it’s sad he will not be caught.

“He should hand himself in. He needs to face up to what he’s done. What made him do what he did?”

Millions viewed CCTV of the shunt online and cops investigated more than 50 “people of interest”.

Cops confirmed in June that the investigation had been dropped - before it was reopened just weeks later on July 13 when "new information" came to light.

A spokesman said: “All 50 people of interest were researched, reviewed and eventually eliminated.

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

The case was shelved only to be reopened when several fresh lines of enquiry emerged.

Met Police confirmed today officers were still pursuing the evidence six months on.

But Colin Sutton, a retired detective chief inspector who solved some of the Met's most notorious crimes, said little could be done with limited money and resources.

He said: “Something that high profile and potentially as dangerous as this, ten years ago, would have had a different level of attention."

Roy Ramm, a former Scotland Yard commander, added: “Somebody will know who this jogger is and perhaps one or two years down the line circumstances might change and they will come forward, but that’s the only remaining possibility that this case will be solved.”
