Police are investigating the second drugs-related death in Galashiels in the space of four days.
The body of an elderly man was discovered at an address in Kirkbrae on Monday evening after concerns had been expressed for his well-being.
The man, who was in his 60s, has not been named.
It is understood there is no connection with the death of 33-year-old David Connolly who was found within a property in Winston Road, Galashiels, on Friday.
There is also no link with the incidents at the weekend when several drug-users were admitted to Borders General Hospital suffering from symptoms of taking Fentanyl.
Police and NHS Borders warned about the risks of a deadly batch of heroin - thought to have been laced with the potent painkiller - being in circulation in the Galashiels area.
