Suu Kyi, 75, has not been seen in public since she was deposed but a member of her legal team, Min Min Soe, was summoned to a police station in the capital Naypyidaw for a video meeting with her.
Demonstrators have hoisted her photos high on street marches and unfurled a huge banner of artwork from a bridge in Yangon depicting the moment she was shot.
A demonstration led by student groups in Naypyidaw was met with force after the gathering had retreated. Police also arrested dozens of the young protesters, though some were later released.
"We aren't doing this for a week or a month -- we are determined to do this until the end when (Suu Kyi) and President U Win Myint are released," one bank employee who had joined the protest told AFP.
Hundreds of protesters had returned to the streets of Yangon on Wednesday morning, where the day before a large crowd faced off against water cannon and a phalanx of riot police near Suu Kyi's residence.
The surge in popular dissent over the weekend overcame a nationwide internet blockade, similar in magnitude to an earlier shutdown that coincided with the start of the coup.
"I have seen many transitions in this country and I was looking forward to a better future," he added, declining to provide a name for fear of repercussions.
