He laboured there with great zeal and success for forty-two years. A victim of the Oates Plot, he was betrayed and arrested at the instigation of a nobleman to whose sisters he was administering the sacraments, and was taken to the Leicester jail. Number one in those parts being willing to bear witness against him, being so universally esteemed, Bentney was at once transferred to Derby, where he was tried and sentenced to death at the Spring Assizes of 1682.
His execution was delayed for unknown reasons and on the accession of James II he was released.
After the Glorious Revolution in 1688, however, he was rearrested, tried and condemned, but the sentence remained suspended, and in 1692 he died in Leicester jail at the age of 83 or 84.
