A second newspaper clipping has been shared. Unlike the first article shared, this one has a visible date, and the main story being reported upon is legible, for the most part. A transcription of the article appears below the image.
United
Herald, Saturday October 17, 1886 - One
Penny
District
Paralysed by Power Failure
Total
outage: Whitchapel, Stepney, Shadwell.
Partial
outage: Wapping, Bethanl Green, Spitalfields, Tower.
Council
authorities have yet to provide an explanation for the loss of electric power
experienced throughout the Whitechapel district. The situation remains unresolved
as this paper went to press, prompting fears that the already notorious neighbourhood
could descend further into disorder with looting and violent [repp...] among
rival underworld factions likely to increase.
The interruption
in electric service is rumoured to have followed an incursion by Her Majesty’s
Knights into the area. The blackout came seconds after a ghastly eruption of
animal noise. Whitechapel’s legion of stray dogs set to a fiendish howling and
were seen rampaging through the streets and alleys.
“It were a
terrible thing to hear. A terrible thing,” claimed one [guttersnipe] who said
he himself heard nothing untoward.
Were the
knights to blame for the sudden disruption? What reason did they have for
violating the Whitechapel perimeter? Officials [b...] quarters remain mum on
the subject. Could terrorists have tampered with the power station, hoping to
instill panic? And do they now plan on escalation to city-wide chaos? Or was
Whitechapel’s well-known reputation as a stockpile of illegal [w]eapons to
blame?
Our readers demand answers.
The incident described occurs in the East London district of Whitechapel, which is probably most famously known for being the location of serial killer, Jack the Ripper's activities. However Jack's five canonical murders only took place after the article above was published. Thus Whitechapel must have been a "notorious neighbourhood" for other reasons in 1886.
From what I've found on Wikipedia, in the early 1880s Whitechapel was primarily inhabited by poorer members of the English working class. There was also an influx of immigrants, primarily Irish and Jewish, and many inhabitants of the district would have been living well be low the poverty line. As such, many of the women were forced to become prostitutes in order to subsidise a families meagre income.
According to a day of the week calculator by Calculator Cat, 17 October 1886 was a Sunday, not a Saturday. I checked 17 October 1880, in case I'd misread the date, but that was a Sunday too.
Of interest is the headline of another article at the bottom of the page, "Additions to the underground planned." This may tie the above clipping to the Railway Map of Central London that was posted shortly afterwards.
