Ms Heper, who has dual Canadian and Turkish citizenship, is a resident of Ontario, Canada.

Canadian authorities have said they are offering consular assistance, but are yet to release any further information over privacy concerns.

It could take at least a month before Ms Heper's case goes to trial, her friend Emrah Bayram told the BBC.

Her friends say Ms Heper suffers from "some health issues" and expressed concern about her access to medicine while detained.

Insulting the president is a crime punishable by up to four years in prison in Turkey.

Lawyers for Mr Erdogan have filed more than 1,800 cases against people, including cartoonists, a former Miss Turkey winner and a 16-year-old student on accusations of insulting him.
