GRAPHIC: Friend who filmed topless mother Natalia Borodina, road sign that hit & killed her, car driven all identified

A woman who filmed a topless mother hanging out of a car window before she hit her head on a road sign and died has been detained by police on suspicion of drink driving.

Natalia Borodina, 35, was filmed hanging topless out of a window during a holiday in the Dominican Republic.

Police have now identified the road sign that killed Ms Borodina and detained her 32-year-old companion Ivanna Boirachuk, from Ukraine.

Tyre marks evidently show the dented red Kia Picanto car butted the yellow kerb at the moment of the tragic accident.

Ms Boirachuk used her mobile to film her friend letting her upper body hang out of the passenger side car window as they drove back from the beach near Punta Cana.

Ms Borodina playfully stuck her finger in her mouth and laughed at the camera, but within seconds, the video shows the impact.

She was rushed to hospital but died of severe injuries.
