Police are investigating the death of a 20-year-old Brazilian woman who died on a bus with 26 iPhones glued to her skin.

The woman, who has not been publicly identified, died of cardiac arrest on July 29, according to multiple outlets, including the Daily Mail.

Cops suspect the young woman was likely smuggling the phones, the Mirror reported.

According to reports, bus passengers informed the police that the woman, who was traveling alone, had fallen ill during the journey from Foz do Iguaçu to São Paulo.

She complained she was having trouble breathing.

People said she collapsed and died when the bus stopped in the city of Guarupuava, located in the central region of Paraná.

Emergency responders tried to revive the woman for 45 minutes, and later said she suffered a seizure.

She was pronounced dead at the scene, according to reports.

While being treated, medics uncovered several packages glued to her body.

As reported by the Daily Mail, the packages contained 26 iPhones. Additionally, police discovered multiple bottles of alcohol in her luggage, the publication stated.

The Paraná Civil Police is waiting on the forensic report before revealing what caused the breathing difficulties and the cardiac arrest.

The cell phones are now in the possession of Brazil’s Federal Revenue Service.
