At this stage of the investigation officers say both incidents are being treated separately.
A murder investigation has been launched into the death of a man who was found with stab wounds at residential premises on the street. At 5.40am, police received calls to say two men had been seriously injured at the property.
One of the injured men was pronounced dead at the scene while the second, a 23-year-old, was taken to Queen's Medical Centre in Nottingham where he is receiving treatment.
Officers have not identified the man who has died nor has his age been ascertained.
A 23-year-old man has been arrested on suspicion of murder.
Ten minutes before the assaults were reported, officers were called to a robbery at the One Stop store on the same street.
Anyone who witnessed the events can call Derbyshire Police on 101 or Crimestoppers, anonymously, on 0800 555 111.
