A jail sentence has been upheld for a man who beat up and robbed a gay man in a park of the British city. Andrew Mark Perry was last November jailed for nine years for the attack.A jury convicted him of unlawful wounding and robbery. In November 2015 Perry and his friend attacked a gay man who was waiting to see a guy he had previously met on Grindr. London’s Appeal Court on Tuesday heard from Perry’s lawyers that they thought evidence used in the November trial was just a casual observation which they believe to be not enough for proving the guilt. “The victim met another man outside the park for a sexual encounter,” explained Judge Jeffrey Pegden QC, “They had arranged to meet through Grindr and went into the woods where they were accosted by two masked men.” Judge Pegden, alongside Lord Justice Lindblom and Mrs Justice Cheema-Grub, rejected the appeal.
