Roy McComb, a former deputy director of the UK National Crime Agency (NCA) from 2014 to 2019, says small-boat crossings across the Channel pose a significant national security threat. In comments reported by the Daily Mail, McComb characterises some of the people arriving via the boats as “young, military aged men,” and argues that the situation should alarm the public. The article frames his remarks as concerns about potential risks linked to cross-Channel migration, rather than focusing on any specific incident. McComb’s position draws on his previous role at the NCA, which is responsible for investigating serious and organised crime and countering threats including criminality that can intersect with border routes. The reporting does not indicate that McComb presents new evidence or identifies particular individuals or groups. His comments reflect an emphasis on security concerns regarding the scale and profile of crossings, while other sources’ viewpoints are not included in the provided material.
