As a report has been in circulation for some days past, that Gravenor Henson and William Robinson, the persons who were deputed to carry the Petition to London, to be presented to the Prince Regent, in behalf of the unfortunate men who have suffered at Leicester, had been taken into custody, it may be proper to give a brief statement of the case, The aforesaid persons after their arrival in London, previous to their calling at Lord Sidmouth’s office, thought it advisable to call upon a gentleman to ask his influence and interest, to give the greater weight to the petition. This, Henson agreed to do himself, and Robinson was to wait for his return in St. James's Park. They had, however, no sooner separated, than a Crown Officer took Henson into custody: Robinson waited about three hours for his companion, in vain. He then returned to their inn, where he learned that an officer, in company with a Nottingham manufacturer, had been, and the officer had seized Henson's box with all its contents. Robinson immediately waited upon the manufacturer, and wished to have an explanation, and to know if there were any charge against him—and said he had no objection to go to the office of Secretary of State, to vindicate himself and explain. In consequence, an officer waiting on him on Saturday, to request his attendance there, but said he was not obliged to attend; however, Robinson chose the accompany the officer, and was introduced to Lord Sidmouth, to whom he stated his object in coming to London; and said he was not conscious of any charge being brought against himself or colleague. The Honourable Secretary, we understand, spoke in terms of approbation, of the frank and undisguised conduct of Robinson, and applauded his motives, but refused him all communication with Henson, who, it seems, is taken up on suspicion of High Treason. A messenger from the Crown arrived at this place on Saturday last, who entered Henson's house, and major a seizure of a variety of papers, which he sealed and took with him to London. Robinson was not arrested, nor his house searched. Henson is at present in Coldbath-fields prison. Such is the information handed to us, and which we believe to be correct.
