The force said a mainland Chinese woman, 26, was spotted behaving suspiciously on Garden Road in Central during the day and was arrested for failing to produce an identity document, while a man, 24, was apprehended at night in Causeway Bay on suspicion of obstructing police officers.
The woman was later released while the man remained in custody for further investigation as of Wednesday night.
The force also said officers took away five men and five women in Wan Chai and Eastern districts for allegedly committing a breach of the peace. Three remained in custody, while the other seven were released after questioning. The 10 were aged between 15 and 69.
Earlier, a source said that police had ramped up patrols in sensitive locations across the city, such as Victoria Park and the central government’s liaison office in Sai Ying Pun, since Monday.
