Police are investigating the suspicious death of Les Ross, a partner in the new Corby nightclub Rubix.
Mr Ross, 39, was found at bed and breakfast accommodation above the shops in The Jamb, in Corby Old Village, yesterday at around 2.40pm with an unexplained head injury.
His family has been notified and a post mortem examination is being held later today (Tuesday, December 18).
Mr Ross was well-known and respected in Corby and many tributes have been paid to him on social networking sites.
He was the business partner of Jon Cowell and the pair opened Lounge 66 and Rubix, in Corporation Street, on December 6.
Mr Cowell said: “We are all devastated. Les was an amazing man and a gentle giant.
“I have known him for 15 years and for the past 12 months we have worked together on the nightclub project. It had been a life-long ambition of his to have a nightclub and we made it happen.
“He was well-known and respected in Corby and was professional in everything he did.”
Corby town centre manager Dan Pickard said: “I worked closely with him as I do with all new tenants. He was a thoroughly nice chap. I had a drink with him on Sunday at a staff Christmas party in the club and he was in good spirits.
“I am saddened and shocked by his death. He was so popular and very well-known in Corby, and a highly respectd man.”
It is understood Mr Ross has family members living in Kettering and in Ireland.
Police have made an appeal for witnesses of any assaults in the Corby town centre and Old Village areas after 2am yesterday (Monday, December 17) to contact the Operation Lane Investigation Team on 101.
