  • In February, protesters peeled bricks from sidewalk to use as projectiles during riots

Hong Kong (CNN)Hong Kong authorities have been gluing down paving blocks to sidewalks, as police roll out heavy security measures during a visit by a senior Chinese official.

Police deployed massive barriers in central Hong Kong, with protests expected during the visit by Zhang Dejiang, who arrived Tuesday. Lawmakers said the bricks were being stuck down to prevent them being thrown as projectiles.
    "I think this is a normal act to do. With the recent bricks throwing incident, there is a need to protect public safety and social order," said Regina Yip, a pro-Beijing lawmaker, on her Facebook page.
    Zhang's trip comes at a time of worsening relations between Hong Kong residents and the central Chinese government, with many concerned about Beijing encroaching on the city's freedoms.
    Police officers stand in front of large barricades erected along a road in Hong Kong on May 16, 2016.
    The heavy policing didn't deter activists, who managed to unfurl two banners. One, on the route from the airport, read "End of the Communist Party dictatorship."
    The other, on Beacon Hill, a local landmark, called for universal suffrage, according to local broadcaster RTHK.
    A leader of pro-democracy street protests in 2014, Nathan Law, was arrested, police said.
    In February, a riot erupted over a government crackdown on street vendors, with protesters hurling bottles and bricks peeled from the sidewalk at police, who responded with pepper spray and warning shots.
    People walk past debris and a section of the pavement which was partially ripped up and used in overnight clashes between protesters and police in the Mongkok area of Hong Kong on February 9, 2016.
    The city's Highway's Department said that paving blocks were generally laid on sand but in some areas, were being strengthened with cement to seal up the joints -- to make them more stable.
    In addition, it said in locations where people assemble, the "paving blocks could be subject to vandalism."

    In 2014, tens of thousands of protesters, many students, took to Hong Kong streets, occupying major roads for 11 weeks in what became known as the "Umbrella Movement."
    The movement was triggered by a political reform package backed by Beijing that would have introduced limited universal suffrage but had been dismissed by pro-democracy campaigners -- as the central government would have pre-selected candidates.
    Since then, the city's government has made it clear that further attempts at reform aren't a priority, and Hong Kong, which as an autonomous city enjoys freedoms unseen across the border, has seen the rise of a major new political faction: the self-described "localist" movement.

    A man with links to Hong Kong's pro-democracy groups was detained in China over a plot to use a drone to disrupt a central government delegation visit to the city, Chinese state news agency Xinhua reported Sunday, without giving further details.
    Police said that they had designated areas where protesters could stage demonstrations during Zhang's visit.
    The Civil Human Rights Front, a pro-democracy group, said it planned to hold a protest Wednesday.
