Ex-scotlandyard detective

Peter Bleksley complains that the police and public service are now “riddled” with baffling initials.

Asked to explain what a CHIS is, he revealed: “A Covert Human Intelligence Source but in old-money, it’s an informant, a snout, a grass, a snitch.”

He said that Line Of Duty writer Jed Mercurio weaves the acronyms in without mercy.these include AC-12, OCG, MIT, PNC andta for starters (anti-corruption unit 12, organised crime group, murder investigation team, police national computer and tactical adviser).

“Sometimes when I watch I just let them go because it’s a long time since I was in the police.

“One that made we chuckle was TFC. I think that means tactical firearms command but at my local cricket club it means, thanks for coming.” Bleksley, former star oftv’s Hunted, continues to work on his own
