A new TV drama about Fraserburgh-born serial killer Dennis Nilsen is expected to air in September.
It was revealed late last year that Scottish actor David Tennant would star as the “Muswell Hill Murderer” in the three-part series.
Images were released showing the Doctor Who star wearing Nilsen’s recognisable glasses and blue shirt.
Written by Luke Neal, Des is based on the book Killing For Company by Brian Masters.
The story is told from the view of Nilsen with Detective Chief Inspector Peter Jay being played by Daniel Mays, and biographer Brian Masters portrayed by Jason Watkins.
After killing for the first time in 1973, Nilsen is believed to have gone on to commit at least 12 gruesome murders while living in London before he was eventually caught in 1983.
The job centre clerk preyed on homeless men and male prostitutes, befriending them and taking them home before strangling or drowning them in his bath.
He would dismember their bodies, and many times either burned the remains in his garden or flushed them down the toilet.
It was the latter method that would eventually lead to his arrest.
He was jailed for life with a recommendation he serve a minimum of 25 years for six counts of murder and two of attempted murder.
Nilsen died behind bars in 2018 aged 72.
In 2016 Nilsen revealed in a series of letters to The Press and Journal why he never challenged or appealed his sentence.
He wrote: “I will not lodge any appeal for release from prison as I owe it to my victims and to justice to serve out whatever time has been allocated to me.
“I have never even thought about lodging an appeal against conviction or sentence and I have always felt this way since day one and nothing has changed in this.”
A spokesman for the series said it is “likely to air mid-September on STV”.
