Police chiefs have laid on extra patrols in a village where they are investigating allegations of a serious sexual assault.
The former hotel was cordoned off by police
Officers said they were not looking for anyone else in connection with the incident and appealed for calm.
They said "a number of males" had been questioned about the alleged attack in Llanybydder, Ceredigion, on Saturday.
In a statement on Sunday evening, the force said it had released the men on bail pending further inquiries.
As part of the inquiry the High Mead Arms Hotel was cordoned off, and a police mobile incident unit set up.
According to local people, the business closed a few years ago and the building has been used for some time to house workers who have moved into the area.
The Dyfed-Powys Police statement did not say how many men were detained or what allegedly happened.
On Monday, police took steps to reassure the community and the surrounding area.
A force spokeswoman said the alleged attack was an isolated incident which occurred within a residential property, but extra police patrols were being laid on to provide reassurance.
People with information are asked to contact police in Aberystwyth on 0845 330 2000.
