Police are hunting a woman for a “hit-and-run” death of the 25-year-old mother who was killed when she was chased on her e-bike and rammed by a Land Rover

Police have launched a manhunt for a woman for a “hit-and-run” after a mother was chased on her e-bike and rammed by a Land Rover in a fatal accident.

Alana Armstrong, 25, suffered “catastrophic” injuries when the SUV knocked her off her bike in Pleasley, near Mansfield, on Tuesday evening.

The rider at the front of the electric bike was injured so badly that his leg had to be amputated.

Now Derbyshire Police have released a CCTV image of a woman wanted in connection with the murder investigation who they believe may have “vital information”.

The woman was pictured outside the White Swan pub in Pleasley wearing a light-colored jumper, matching trousers and white trainers.

She was also of average height and build, with dark hair pulled back in a ponytail.

Ms Armstrong was the mother of a six-year-old boy who is now struggling to make sense of her sudden loss with Christmas just weeks away.

Two people were arrested but have now been excluded from the murder investigation.

“Two people arrested in connection with the incident have now been released without charge – and excluded from our investigation.

“We have already received a lot of information from the public and I would like to thank everyone who has already come forward to assist our investigation.”
