After two years away from our screens, Line of Duty came back with a bang on Sunday evening with a brand new murder case and viewers were delighted.

Series 5 wrapped in 2019, where we saw Superintendent Ted Hastings managed to avoid being framed as the elusive H. He is still leading the team at the anti-corruption department alongside DS Steve Arnott.

The highly anticipated sixth series gave viewers several plot twists but there was one mystery in particular which left some viewers very confused.

Line of Duty returned on Sunday with new character Detective Chief Inspector Joanne Davidson (

One of the new terms viewers discovered was CHIS was used a lot especially by new character Detective Chief Inspector Joanne Davidson (Kelly Macdonald) and DI Kate Flemming (Vicky McClure) who were investigating the murder of journalist Gail Vella.

"How many people have googled 'what is a CHIS' tonight?" tweeted one viewer. Don't worry, we had to Google it too.

Another person joked, "CHIS. Never heard the word before this episode of #LineOfDuty and I think I've now heard it more than any other word in the English language."

People had to Google what CHIS stood for (

A third Twitter user shared: "2.7 million acronyms so far. CHIS being the most popular".

"Give the voiceover woman at the end of #LineOfDuty a pay rise for explaining what CHIS means!" said another.

The BBC announcer explained what CHIS meant after the episode finished on Sunday night (

After lots of Google searches and tweeting from fans, the official Line of Duty Twitter account confirmed that it stood for Covert Human Intelligence Sources, before the BBC announcer confirmed it after the episode aired.

The first episode also revealed that long-term AC-12 member Kate is now working with a new team.

One person joked they've heard CHIS more than any other word (

It's going to be a tough series for AC-12 as they continue to investigate the unsolved murder of Gail Vella.

Supt Ted Hastings, DI Kate Fleming and DS Steve Arnott are now required to investigate DCI Joanne Davidson, "the senior investigating officer of an unsolved murder, whose unconventional conduct raises suspicions at AC-12."

According to Adrian Dunbar, who plays Hastings, things are still looking murky for Ted - and for AC-12 as a whole - at the start of season six.

"Quite a lot has happened and there's been quite a time jump," Adrian explains. "In his working life, a lot of things have destabilised which have affected the unit. I think he's another year older but not another year wiser.

"Let's face it -time is running out a bit for Ted; the age he is, whether he can stay in the force, is he useful enough, is he a bit of a dinosaur? He's up against quite a bit. His personal life is not in great shape."

Even the Line of Duty Twitter account responded (

And judging by her icy cold demeanour, she could be their toughest and most slippery adversary yet - with the tension of the high-risk case clearly getting to the rest of AC-12 as seen in the first look.

Line of Duty returns to BBC One and BBC iPlayer on Sundays at 9pm.
