A Roman Catholic priest is "utterly shattered" that police looking for a missing woman have found a body in his Glasgow church.
Angelika Kluk failed to turn up to work on Monday
Angelika Kluk, a 23-year-old Polish student, had been living at St Patrick's Church, where Father Gerry Nugent is the priest.
A post mortem will be carried out on the unidentified body.
Strathclyde Police said that Peter Tobin, the man last seen with Ms Kluk, was a registered sex offender.
Ronnie Convery, the director of communications at Glasgow's Roman Catholic Archdiocese, said everyone was horrified at the find and that Fr Nugent was "utterly shattered" when he heard the news.
Mr Convery added: "It is almost unbelievably horrific.
"The idea that a body could be found in or around a church almost defies belief.
"Obviously, those most directly affected are shattered by this news.
"Father Gerry Nugent, who's been spending every waking hour for the past week trying to help the police, has been asked to leave the premises because the whole place is sealed off.
"He's completely shattered by this news."
Strathclyde Police Detective Superintendent David Swindle said that it was too early to give any further details regarding the identification of the body.
He made a further appeal for Peter Tobin to come forward.
Ms Kluk was reported missing on Monday after she failed to turn up for work.
Tobin had been doing odd jobs at the church and had been known by the congregation as Pat McLaughlin.
Police said that 60-year-old Tobin had supplied officers with a false name, address and age before vanishing just days after the student went missing.
The last known address for Tobin, who was jailed in 1994 for raping a 14-year-old girl and indecently assaulting her friend in Hampshire, was in Paisley.
Police said the body was discovered at 2000 BST on Friday, after a detailed search of the church premises.
Earlier on Friday, police revealed that the man last seen with Ms Kluk was a registered sex offender.
This was the second summer the language studies student had stayed in Glasgow, where her sister Aneta, 28, works as a secretary. She had already bought her ticket home.
On Saturday, officers stood guard at the church entrance and a police cordon has been put in place across the gates to the chapel house.
Tobin became involved with the chapel about two months ago through the local homeless group Loaves And Fishes.
