Legal analysis: the premise of police arresting people is to receive a report from the bank and then file an investigation. After collecting the evidence, the police will come to arrest people. Of course, this does not rule out the possibility of arresting people at home during the investigation stage. After all, public security organs can detain criminals or major suspects.

Legal basis: Article 82 of the Criminal Procedure Law of People's Republic of China (PRC), under any of the following circumstances, the public security organ may detain a flagrante delicto or a major suspect in advance: (1) a person who is preparing to commit a crime, commits a crime or is found immediately after committing a crime; (2) The victim or a witness on the spot identifies him as a criminal; (3) criminal evidence is found around him or at his residence; (four) attempted suicide, escape or escape after committing a crime; (5) It is possible to destroy or forge evidence or collude with others; (six) do not speak the real name and address, the identity is unknown; (7) Being seriously suspected of committing crimes on the run, committing crimes for many times or committing crimes in association.
