Six masked protesters surrendered early Friday morning in Hong Kong, bringing to about 30 the number that have come out in the past day from a university campus surrounded by police.
The group emerged from a campus entrance and held hands as they walked toward a checkpoint around 3 a.m. Five wore the black clothing favored by the movement and the other was in a blue checked shirt.
Most of the protesters who took over Hong Kong Polytechnic University last week have left, but an unknown number remain inside. Police are arresting all the adults. Those under 18 can go home but may face charges later.
The anti-government protesters battled with police and blocked the nearby approach to a major road tunnel, which remains closed.
It was the latest bout in more than five months of unrest in the semiautonomous Chinese territory. Protesters are demanding fully democratic elections and an investigation into alleged police brutality in suppressing the demonstrations.
Anti-government rallies were held in at least two places Thursday night. Riot peace kept watch, exchanging heated words with some, but there were no major clashes ahead of district council elections on Sunday.
Protesters fear that the government could cancel the elections because of the unrest. City leaders have said they want to go ahead with the vote but warned that violence could make it impossible to hold a fair and safe election.
The election is seen as a bellwether for public support for the protests.
