A ghoulish police officer narrowly avoided prison after stealing a debit card and driving licence - from a dead man.
The Army veteran's "despicable" theft, in January 2017, was uncovered when his home was searched after a female PC accused him of being a Peeping Tom.
But while disgraced Darby was acquitted of voyeurism, during the raid by his colleagues, four bank cards were found stashed in a bag by his bed, along with Mr Steel's driving licence and bank card stolen form his home in Maida Vale.
The others were stolen from his former housemates from a flat he used to share with police colleagues in Wimbledon.
Darby did not use any of the cards and when asked to explain why the cards were there he said he had 'no idea'.
Darby, of Camberwell Green, appeared for sentencing for three counts of theft at Blackfriars Crown Court after being convicted by a jury earlier this month.
He was sentenced to do 200 hours of unpaid work with 20 days of rehabilitation during a 12-month community order.
Recorder Richard Smith described the thefts as "opportunistic" but did not say they were "financially motivated".
He said: "Your conduct in stealing his personal possession was the very antithesis of what would be expected of a police officer."
But nothing Darby received "commendations" for his military service said he should receive a custodial sentence.
He said: "Until this point in your life you have had an unblemished record.
"Second independent of the sentence I shall impose, your convictions have already had and will continue to have significant adverse consequences for you and your family.
"Third your risk of reoffending is low."
Earlier today prosecutor Oliver Doherty, referred to thefts that resulted in prison sentences and said stealing from a dead man "could perhaps described as in the same way, as a despicable offence".
He added: "There can, says the Crown, scarcely be a higher degree of trust put in somebody than a serving police officer entrusted to go into a citizen's house and that's why we say it's high culpability.
"The postal system only works if people respect the sanctity of it, if that's an appropriate word."
Heather Oliver, mitigating, said: "He's an Army veteran, he served his country for 16 years, he served his community as a police officer for nearly five years.
"Mr Darby is very shortly to be without an income and he will struggle to find employment given these convictions."
Last year Darby was cleared of leering at a female officer as she took a shower at a shared section house.
The ex-Royal Engineer Lance Corporal always denied the allegation and told Inner London Crown Court.
During his evidence, he said: "I know the difference between right and wrong, I was in the army. I've got morals, I've got standards."
He was found not guilty of observing a person doing a private act for his sexual gratification on January 9 2018.
Darby was ordered to pay £1,500 contribution to prosecution costs and declined to comment after leaving the court.
