State Counsellor Aung San Suu Kyi was arrested on Wednesday and charged with illegally importing and using communication devices found in her home days after she was detained by military forces in Myanmar.

According to a police request to a court, accusations against Nobel Peace Prize laureate Suu Kyi alleged six walkie-talkie radios were discovered after authorities searched her house in the capital city of Naypyidaw. The devices were allegedly imported illegally and used without permission.

If convicted, 75-year-old Suu Kyi could face up to three years in prison. For now, she remains in custody until Feb. 15 and is reportedly confined to her home.

On Monday, the country's military seized power on unverified claims the country's November elections were fraudulent. Suu Kyi's National League for Democracy reportedly won in a landslide, though disagreeing authorities plotted for her arraignment earlier this week.

President Biden declared on Tuesday the situation in Myanmar to be a "military coup," referring to Suu Kyi as the "duly elected head of government," and he threatened sanctions against the country. The Group of Seven has also condemned the coup.

Charles Santiago, chairman of the Association of Southeast Asian Nations' human rights division, said charges against Suu Kyi were unfounded.

Myanmar was under military rule from 1962 to 2011 before it became a civilian-led democracy in 2011.

Suu Kyi spent 15 years of her life under house arrest from 1989 to 2010 while leading the country's democracy movement. Since her Monday arrest, protests have emerged by some residents opposing the coup.
