The heartbroken family of a woman who died four months after being struck by an e-bike spoke of their “unimaginable” pain, as police arrested a teenager over her hit-and-run death.
Julia Burns, 62, suffered serious injuries as she crossed Elmwood Avenue, Feltham.
Police were called to reports that a pedestrian had collided with an electric bike in Hounslow at approximately 7.45pm on September 29 last year.
London Ambulance Service took Mrs Burns to hospital where lost her fight for life on February 13.
The rider left the scene before officers arrived.
On July 24, a 19-year-old man was detained on suspicion of causing death by dangerous driving.
He has been released under bail pending further enquiries until a date in October, the Metropolitan Police said.
In a statement, Mrs Burns loved ones said: “Our family is devastated by the tragic loss of our beloved Julia.
“Her absence has left a void in our lives that can never be filled.
“Julia was the heart and soul of our family, and her loss has left us heartbroken beyond words.”
“The trauma Julia endured—and the heartbreak we experienced beside her—was unimaginable. No family should ever have to watch a loved one suffer the way she did.

“We are pleading with anyone who may have information to please come forward.
“Even the smallest detail could make a difference.
“Your courage and compassion could help bring justice for Julia.”
Detective Constable Sarah Royle, from the Met’s Serious Collision Investigation Unit, said: “Our thoughts are with the loved ones of Julia, who have endured so much throughout this difficult time.
“Investigators have been working continuously on this incident for the past year, to try and piece together the circumstances that sadly led to Julia's death.
“Were you in the area this time last year and recall seeing or hearing the incident? Perhaps you saw something suspicious in the moments afterwards?
