I beg to report with reference to the occurrence in New Street (formerly Hand Alley), that whilst conducting routine patrol along the eastern perimeter of Bishopsgate, I entered said street at approximately 4:15 a.m. Upon turning the bend, I discovered a scene of considerable violence.

A female, since identified as Clara Fenwick, was found lying upon the cobbles, her person exhibiting signs of mutilation. Adjacent to her body lay PC James Thomas Reeve, deceased, clutching a silver locket engraved with the initials “J.T.R.”. A third individual, Sergeant Arthur Melrose, was also present, having sustained fatal injuries consistent with a struggle.

The alley floor bore scattered surgical implements, including scalpels and blades. The wounds upon Miss Fenwick bore resemblance to the engraving upon the locket. It is the opinion of this officer that PC Reeve was the assailant, and that Sergeant Melrose perished in the execution of his duty.

A witness, a male child of vagrant appearance, was located in Rose Alley. Said child reported hearing a man proclaiming himself to be “Jay Thompson Rivers” and declaring, “I am Jack the Ripper.”

The scene was secured and notification sent to Bishopsgate Station. Awaiting further instruction.
