According to a security source, Aung San Suu Kyi returned to her villa an hour later.
The move follows a bloody crackdown on pro-democracy protests in Yangon and elsewhere in the country that human rights groups say left hundreds dead.

In the wake of the crackdown Myanmar's military rulers have been under growing international pressure to open a dialogue with the opposition.
Earlier this month the UN special envoy to Myanmar, Ibrahim Gambari, urged Myanmar's military rulers to appoint an intermediator to begin talks with the opposition during a visit to the country.
Aung San Suu Kyi - leader of the main opposition party, the National League for Democracy (NLD) - has been under house arrest for most of the past 18 years.
She was seen briefly at the gates of her home offering prayers for marching monks at the height of last month's anti-government protests.
She also held two rounds of talks with Gambari during his visit to Myanmar after the military crushed the protests.
The NLD won a landslide victory in national elections held in 1990, but the military refused to recognise the result.
