A statement by military leader Min Aung Hlaing, who led the coup, said he had "commuted her remaining sentence to be served at the designated residence". BBC reported.
Aung San Suu Kyi came to power in 2015 after Myanmar's then rulers introduced democratic reforms. Before that, she spent decades of military rule as a pro-democracy activist, and was previously held for more than 15 years under house arrest.
State media broadcast a picture of her sitting with two uniformed personnel.
Her son Kim Aris said he was sceptical about the announcement and that he did not even have proof that she was alive. He said the picture was "meaningless" as it was taken in 2022.
