David Ross death: Youths 'challenged' outside dead man's home
Police said they wish to speak to a man who challenged youths outside a nightclub owner's home just days before he was found dead in a hotel room.
David Ross' body was found with head injuries at Corby's Village Express in Northamptonshire on 17 December.
The 39-year-old's house on Chelveston Drive was burgled three days before and a laptop was among the items taken.
Police said a man challenged some youths on the night of the burglary and have asked for him to come forward.
Det Ch Insp Martin Kinchin said: "We know a man standing in the area of Les's home shouted at a number of young men around this time.
"We are conscious that this incident might be completely unconnected to the burglary and may be nothing untoward, so we ask anybody who was shouting, or who was being shouted at, in Chelveston Drive around this time to make contact with the police."
Mr Ross - known as Les - opened the Rubix nightclub in the town with his business partners two weeks before his death.
He was burgled while at work and it led to him stay at the hotel. His home had also flooded.
Police previously said Mr Ross had borrowed money to open the club, but it was unclear whether it was related to the killing.
Last month Mr Ross' case featured on BBC Crimewatch and a reward for information related to his death was doubled to £10,000.
So far three men from the town have been arrested and bailed over the burglary.
