Myanmar police have filed several charges against the elected civilian leader Aung San Suu Kyi following Monday's military coup.
Suu Kyi has been remanded in custody until 15 February, police documents showed, reports the BBC.
The charges include breaching import and export laws, and possession of unlawful communication devices.
Her whereabouts are still unclear, but it has been reported that she is being held at her residence in the capital, Nay Pyi Taw.
Deposed President Win Myint has also been charged, the documents show - in his case with violating rules banning gatherings during the Covid pandemic. He has also been remanded in custody for two weeks.
Neither the president nor Suu Kyi have been heard from since the military seized power in the early hours of 1 February.
The coup, led by armed forces chief Min Aung Hlaing, has seen the installation of an 11-member junta which is ruling under a year-long state of emergency.
The military sought to justify its action by alleging fraud in last November's elections, which Suu Kyi's National League for Democracy (NLD) won decisively.
The accusations are contained in a police document - called a First Initial Report - submitted to a court.
It alleges that Suu Kyi illegally imported and used communications equipment - walkie-talkies - found at her home in Nay Pyi Taw.
She was remanded in custody "to question witnesses, request evidence and seek legal counsel after questioning the defendant", the document says.
Win Myint is accused, under the National Disaster Management Law, of meeting supporters in a 220-vehicle motorcade during the election campaign in breach of Covid restrictions.
