A second protest has been staged outside a Gloucester bail hostel where high-risk offenders could be housed.
The bail hostel could take category A offenders from October
Objectors who took part in Saturday's action fear murderers, rapists and paedophiles may be placed at the Ryecroft premises from October.
But the Probation Service claimed anyone thought to pose a threat to the public would not be admitted.
Fourteen years ago council worker Anna McGurk was murdered by one of the inmates at the hostel.
The campaign is being led by Community Against Ryecroft Policy (Carp).
Its members argue Ryecroft is not suitable for such offenders because there are several schools, a city farm and many families in the area.
One protester said: "It's a residential area. You don't put the most dangrerous criminals in a residential area when they come out of prison."
