• Tamzin Hall, 17, died after she was hit by a car on a U.K. highway shortly after she managed to exit a police vehicle pulled up on the shoulder

• An investigation is ongoing and the two police officers in the vehicle have been served "misconduct notices for a potential breach of their duties and responsibilities"

• "Tamzin was my absolute everything and I can’t believe she isn’t here anymore," the late teenager's mother said in a police release

A teenage girl died after she exited a stationary police vehicle on the highway shoulder, according to authorities in England.

On Nov. 11 at around 10:40 p.m. local time, Tamzin Hall, 17, was arrested "following a disturbance" at an address in the town of Taunton, Somerset.

Midway through being transported by two Police officers to a custody suite in the nearby town of Bridgwater around 12 miles away, she left the vehicle and ran across the highway before she was struck by another car, per a release shared by The Independent Office for Police Conduct (IOPC), which is investigating her death.

"Initial evidence suggests that Tamzin was handcuffed to the front and placed in the rear of a marked police Toyota Corolla. An officer was sat alongside her," the release stated.

The IOPC said that "an early account from the police driver" indicated that just before 11 p.m., the teenager managed to escape from the stationary car after officers pulled over the M5 highway for safety reasons.

The release added that soon after Tamzin managed to exit the car, she was "involved in a collision with a vehicle driven by a member of the public, on the southbound carriageway."

"Despite the attendance of paramedics, Tamzin sadly died at the scene," the IOPC said.

Both officers have been served with "misconduct notices for a potential breach of their duties and responsibilities," the release continued. It added that IOPC investigators had looked at bodycam footage and CCTV, as well as taking witness accounts.

An inquest into Tamzin's death was opened and adjourned earlier this week, the release confirmed.

“My thoughts and sympathies remain with Tamzin’s family and friends, and everyone affected by the tragic events of that evening," IOPC Regional Director, David Ford, said, per the release.

“We have met with Tamzin’s family to offer our condolences and to outline how our investigation will progress. We will provide them with regular updates as our [inquiries] continue," Ford added.

“Our investigation is in the early stages and we are working hard to establish the exact circumstances of what took place, from the time of Tamzin’s arrest, to how events unfolded a short time later on the M5,” he continued.

Tamzin's mother, Amy Hall, paid tribute to her daughter — who was diagnosed with autism spectrum disorder — in a police release.

“Tamzin was the most kindest, caring, loving, loyal girl ever. She was the most honest person I’ve ever known; she was very special to me," Amy said. “She had a great sense of humour, and we had many laughs together."

“She was my shadow from the moment she opened her eyes in the morning until she went to sleep at night. She was such an intelligent young girl and had such interesting perceptions on things in life,” she added.

Amy continued, “Tamzin was my absolute everything and I can’t believe she isn’t here anymore. She was my world. She put her all into absolutely everything. She loved helping out as a young child, if you set her a task, she would put her all into it and want it just right."

“Tamzin was such a wonderful daughter. She was a beautiful person," Amy's tribute included. “My life will never be the same but I’m using my strength for my other children, Tamzin’s siblings."

“She was only 17 but she has taught me a lot and I can use that memory and hold on to that," she shared. “I will never ever get over it, she was taken far too young.”
