At the time of the conversation, the men’s mother, Kiran Kaur, and father, Moga Singh, were also in police custody.
Gurpreet and his father were arrested minutes after Digwa, followed by Kiran Kaur about 90 minutes later.
The brothers discussed how their parents might be coping and how they would be affected if Digwa is convicted.
Digwa said: “Mum was making a lot of noise. It was my fault.”
Kiran Kaur was convicted of assisting an offender after removing the murder weapon from the scene at Digwa’s request. She is due to be sentenced later this month.
“You and the father, nothing will happen,” Digwa said.
Neither Gurpreet nor his father faced charges in relation to the murder.
However, both Gurpreet and Vickrum Digwa and their father, Moga Singh, were charged with multiple weapons offences, dated the same day Henry Nowak was declared dead by medics.
All three have pleaded not guilty to possessing weapons, including machetes, knuckledusters, flick-knives and 37 swords, in a private place, at the family home in St Denys Road, Southampton.
Gurpreet Digwa has also pleaded not guilty to an additional four charges of possessing weapons in a public place, in a car in Belmont Road.
The three men are due to stand trial at Southampton Magistrates’ Court in September 2027.
