The UK’s National Crime Agency has arrested four people over a series of disruptive cyberattacks that targeted leading British retailers earlier this year.

The authorities detained three teenage males and one 20-year-old female in the West Midlands and London on suspicion of Computer Misuse Act offenses, blackmail, money laundering and participating in the activities of an organised crime group, the agency said in a statement Thursday.
