The actor, who played DSI Ian Buckells in the police drama, certainly had a spring in his step after fans were left underwhelmed by the revelation that he was the man at the heart of the organised crime operation.

Seasoned fans took to social media in their droves to share their frustrations as officers from the police anti-corruption unit AC-12 discovered the identity of the elusive ‘fourth man’, who had been colluding with the organised crime group (OCG), was none other than DSU Ian Buckells.

The detective was first introduced to viewers in series one when he was appointed as SIO in the case of murdered businesswoman Jackie Laverty by then chief superintendent Derek Hilton. 

However, the episode’s end failed to offer any resolution on whether the fan-favourite team of DI Steve Arnott, DI Kate Fleming and Superintendent Ted Hastings would return, ending on the revelation that the team has ‘never been weaker.’

The mystery surrounding the identity of ‘H’ has been up for speculation since the show was first released in 2012 and detectives at the anti-corruption unit discovered there were four officers working within the force who had links to the underground criminal network. 

During the episode tonight, superintendent Ted Hastings, played by actor Adrian Dunbar, was seen asking his colleague Chloe to run checks on the constant misspelling of the word ‘definately’ which had become synonymous with the ‘fourth man’ in previous episodes.

A number of checks traced the word back to Buckells who used the misspelling when messaging former undercover officer John Corbett, played by Stephen Graham, in series five.

When confronted with the revelation Hastings was left astounded, asking his colleague: ‘Are you sure Chloe?’

After being confronted by Hastings and his team Buckells declared: ‘I’m only the one whose made total mugs out of you lot!’.

He also revealed that would have to offer him immunity or Witness Protection if they wanted him to co-operate.

Pointing out that H did not officially exist as the investigation into corruption had been quashed, he insisted Tommy Hunter, the organised crime kingpin who was a sinister character during the drama’s early series, was the leader of the OCG.

Finally! AC-12 finally figured out H's identity when they saw he'd used the same 'definately' misspelling used by the criminal throughout the series
