HATTON GARDEN.—For some time past, numerous complaints have been made to the magistrates of this office of two penny theatres, one in Mortimer Market, Tottenham Court Road, and the other in a field adjacent to Bagnigge Wells Road, where gangs of young thieves nightly assembled. On Wednesday last, several inhabitants of Mortimer Market attended at the Office to complain of the former establishment, when Mr. Rogers granted a warrant to apprehend the whole of the parties concerned, and on Thursday night, Duke, Baylis and Halls, of this Office, in company with Inspector Jenkins and a body of constables, proceeded to the theatre, and captured the manager, performers, and musicians, and the whole of them were, yesterday, brought to the office, and placed at the bar, when the office was excessively crowded. There were twelve prisoners, some of whom were attired in their theatrical habiliments, with their countenances painted, which made a very grotesque appearance. Duke being sworn, stated that, in consequence of a warrant, on Thursday night last, about 9 o’clock, he proceeded, with other officers, to a penny theatre in Mortimer Market, St. Pancras, where he found the whole of the prisoners, some of whom were engaged in performing their parts, whilst Ewyn, the manager, was employed in taking money at the doors, and the woman, Green, was acting as check taker. Campbell and Lewis were enacting their parts upon the stage, and Joseph Burrows was in his theatrical dress between them, with his face painted and wearing a huge pair of moustaches. John Pillar was in a temporary orchestra with a large violoncello, scraping away most melodramatically, whilst the players were endeavouring to humour the sounds, and to suit their action to the word, and the word to the action; and just at that part of the performance when Burrows had to exclaim, “The officers of justice are coming,” witness and his brother officers rushed upon the stage, and apprehended the whole of them. Mr. Rogers: What description of audience was there? Duke: A dirty, ragged set, principally consisting of boys and girls; two of them were barefooted, and had scarce a rag to cover them, and did not seem to have been washed for a month. The theatre was of the most wretched description; there was a temporary stage, and bits of scenery. The boys said they were errand boys and servants. Brierly and Smith said they were country actors out of an engagement, and had visited the place out of curiosity. Mr. Mallett: Had they an inscription that they were “Licensed pursuant to Act of Parliament”?
