The UK National Crime Agency (NCA) has arrested four people suspected of taking part in recent cyberattacks against M&S, Co-op, and Harrods. An NCA press release said the police apprehended two 19-year-old males, one 17-year-old, and a 20-year-old female in the West Midlands and London, all of whom had their electronic equipment seized.

Four people have been arrested after a wave of cyber attacks struck Marks & Spencer, Co-op and Harrods this year. A woman and three teenagers were arrested early yesterday morning on suspicion of blackmail, money laundering, offences linked to the Computer Misuse Act and participating in the activities of an organised crime group.
