Two men accused of posing as underage teenage boys on Grindr in order to blackmail older users are denying the offences.
Nathaniel Foster and Adam Webb, both 25, had originally pleaded guilty to two charges of blackmail.
However, since an earlier court hearing both men have asked for permission to change their pleas to not guilty and requested a trail by jury.
Normally, if suspects plead guilty, they can be sentenced without a full jury trial.
Sitting at Gloucester Crown Court, Judge William Hart ruled that full applications to change their pleas would have to be made in writing and considered early this month.
The defendants are accused of attempting to demand money with menaces from two men.
It is claimed that one victim paid out £15,000 but the second – who was allegedly asked to pay £10,000 – alerted the police, the Stroud News and Journal reported.
The defendants allegedly posed as 15-year-old boys on the app in order to lure the older men, who cannot be named for legal reasons.
Foster, whose address is in Wheatstone Road, Gloucester, and Webb, of Kingsway, Quedgeley, were remanded in custody.
The pair had both previously been on bail, the newspaper said.
