Ousted South Korean leader Park Geun-hye is keeping her silence as calls grow for her arrest.
Ms Park was forced from office on Friday, after judges unanimously upheld parliament’s decision to impeach her over her role in a corruption scandal involving close friend, Choi Soon-sil.
Despite the ruling, she remains inside the presidential compound.
Thousands turned out for rallies in Seoul on Saturday, a day after three people involved in protests died there.
Many were calling for Ms Park’s arrest, although a smaller number of her supporters also gathered in nearby streets.
There are fears the two sides may clash and there is a heavy police presence.
A spokeswoman for the protesters supporting the court’s decision, Choi In-sook, told Reuters they were demanding the arrest of their former leader.
Ms Park has lost her presidential immunity and could face criminal charges.
Meanwhile, the country’s election commission announced a “free and fair” vote would be held by 9 May at the latest.
