Dozens of Myanmar protesters who were trapped overnight by security forces have now fled the premises.
Around 200 people in a district of Yangon had on Monday been blocked from leaving a four-street area in the Sanchaung area of the city on Monday.
Of this, at least 40 people were arrested and taken away overnight, a local resident told BBC News.
Others managed to escape in the quiet hours of the night as police numbers dwindled.
Mass protests have been seen across the South-east Asian nation since the military seized power on 1 February in a coup.
At least 54 people have died in the protests, which are calling for an end to military rule and the release of the country’s elected government leaders – including Aung San Suu Kyi – who were overthrown and detained in the coup.
