Line Of Duty viewers saw the funny side after spotting a spelling mistake in the latest episode of the crime drama.
Sunday’s instalment of the BBC show saw officer John Corbett (Stephen Graham), who is deep undercover as a baddie, communicating with mysterious crime boss H.
One of the messages he received read: “Eastfield depot is definately high risk.”

Fans could barely contain themselves about the word “definitely” being spelled incorrectly.
While a few people thought it was a production error, most divined that it was a very deliberate part of the script, to point out H has gaps in his spelling knowledge… and something that may possibly expose him.
“Any chance of some correct spelling on #LineOfDuty,” asked one person on Twitter.

“I can’t get over the spelling error in #LineOfDuty. If you put an ‘a’ in ‘definitely’ you are definitely a criminal,” joked one person.
