Myanmar elected civilian leader Aung San Suu Kyi has been remanded in custody until 15 February following Monday's military coup, Reuters reported on Wednesday.

Myanmar's army seized power on Monday, detaining Nobel laureate Aung San Suu Kyi and cutting short a transition to democracy in a takeover that has drawn condemnation from the United States and other Western countries.

A police request to a court detailing the accusations against 75-year-old Nobel laureate Suu Kyi said walkie-talkie radios had been found in a search of her home in the capital, Naypyidaw. It said the radios were imported illegally and used without permission.

The document reviewed on Wednesday requested Suu Kyi's detention "in order to question witnesses, request evidence and seek legal counsel after questioning the defendant".

A separate document showed police filed charges against ousted President Win Myint for offences under the Disaster Management Law.
