This is the moment Ian Stewart was arrested on suspicion of murdering his partner Helen Bailey.
The 56-year-old was still in bed when police entered the couple's home in Royston last July.
He then came downstairs in his dressing gown, and reacted with surprise when officers told him he was being arrested.
The whole incident was captured on a bodycam worn by one of the officers present.
The following day Helen's body was found in a cesspit under the garage.
The man who led the investigation into the murder of children's author Helen Bailey's has described her killer Ian Stewart as a "particularly wicked individual."
56-year-old Stewart was found guilty of drugging and killing Ms Bailey in a murder plot driven by money.
Speaking outside St Albans Crown Court, Detective Chief Inspector Jerome Kent said he was glad to see Stewart behind bars.
"He must be a particularly wicked individual," Mr Kent said.
"He purported to love her, and yet not only can he kill her, but then he can dispose her body into a cesspit and eventually tell lies in open court.
"It's the mark of a very wicked by quite calculated individual."
Three men from the Ipswich area have been arrested following a stabbing in the town.
A 46-year-old man was stabbed in the torso following a fight between three men close to the roundabout on the A137 between Hawes Street and Virginia Street on Tuesday 21 February.
His injuries aren't life-threatening though and he remains in hospital under arrest on suspicion of attempted murder.
Another 46-year-old man suffered a cut to the face and was also arrested on suspicion of attempted murder, while a third man aged 31, was arrested on suspicion of affray.
Police have confirmed they will reinvestigate the death of Ian Stewart's first wife Diane Stewart following his conviction for the murder of his fiancé Helen Bailey.
Mrs Stewart died in 2010, with an inquest finding that she had an epileptic fit in the garden.
Det Ch Insp Jerome Kent was quick to point out at St Albans Crown Court that there is currently 'no suggestion Diane Stewart died of anything other than natural causes', but admitted that the Helen Bailey murder trial potentially opens up new suspicion.
