Police have launched an investigation following the sudden death of a man in Dundee city centre.
Emergency crews were called to St Andrews Street shortly before noon on Thursday after a man’s body was discovered in a flat.
A spokesman for Police Scotland said the death was being treated as unexplained.
The man – named locally as Paul Lamont – is understood to have lived in the area for about 10 years.
A resident contacted the emergency services after knocking on Mr Lamont’s door and receiving no answer, which he said was unusual.
Entering the property, he found Mr Lamont unresponsive.
The tenant – who declined to be named – had gone to visit Mr Lamont before discovering him in the bedroom.
He said: “I’m devastated at the sudden loss of Paul.
“He was a quiet guy, he was only 51 years old and was originally from South Africa.
“I chapped on his door yesterday morning – I was going to be giving him a bed frame.
“He didn’t leave his flat that often and I knew something wasn’t right when he never answered.
“Paul had given me a key as I delivered him messages and checked on him to make sure he was OK.
“I went into the bedroom and found he was unresponsive and contacted the emergency services.
“To their credit they were here in under a minute.
“It’s all just an incredible shock. I had only spoken to him the night before and he was fine.”
Another resident also paid tribute to her neighbour.
She said: “He was a lovely man and such a nice guy to speak to. This has all come as such a shock.
“Emergency crews were here very quickly.”
Shoppers watched two ambulances arrive at the property before police were seen “rushing” into the block.
At least six officers were seen entering the block.
A spokesman for the Scottish Ambulance Service confirmed it attended and the matter was now being dealt with by Police Scotland.
A police spokesman said: “Officers attended an address on St Andrews Street following the sudden death of a man.
“His death is being treated as unexplained at this time.”
