A woman called police to thank them after a traffic stop for suspected drunk driving - led to the discovery of a brain tumour.

Tamara Palmer was stopped by two officers in December last year after her vehicle hit "the curb multiple times and failed to maintain its lane”.

Police footage, from dashboard and body-worn cameras, show Senior Police Officer Raymond Schoonmaker and Patrolman First Class Bret Aton pulling Tamara over.

Tamara, a teacher, from Mount Pleasant, South Carolina, USA, didn’t show signs of intoxication, but complained of vision problems and a headache.

“I think something medical is going on with you and you really need to go to the hospital,” officer Schoonmaker told Tamara.

A spokesman said: “The officers determined that Ms. Palmer was possibly having a medical episode and requested an ambulance."

Once at the hospital, doctors found a large brain tumour and performed an emergency operation to remove the tumour.

The op was a success and Tamara was discharged from the hospital in a matter of days.

Tamara has now fully recovered contacted the Mount Pleasant Police Department to let them know that the officers who pulled her over saved her life.
