A five-day police operation targeting organised immigration-related crime results in hundreds of arrests across the UK, according to reports from multiple outlets citing the National Police Chiefs’ Council. Police say the crackdown focuses on illegal trading and exploitation linked to organised immigration offending. During the operation, law enforcement officers seize more than £1 million in cash and recover goods connected to the suspected criminal activity. The Mirror reports that the bust leads to more than 300 arrests, while the BBC similarly states that there are more than 300 arrests tied to the organised immigration crime crackdown. Both accounts describe the action as a coordinated effort involving police resources over several days, aimed at disrupting criminal networks and seizing the proceeds of crime. Details including the specific locations of arrests, the types of goods seized, and the nationalities or identities of those detained are not provided in the supplied summaries. No outcome in terms of prosecutions or court appearances is reported in the sources referenced.
