Fears are growing for the safety of a young missing Polish woman.
Angelika Kluk was due to return to Poland next week
Student Angelika Kluk, 23, was last seen in the grounds of St Patrick's Chapel in the Anderston area of Glasgow on Sunday.
She was reported missing after failing to turn up for her cleaning job. She was due to return home on 2 October.
Her sister, Aneta Kluk, 28, appealed for information. She said: "We are very worried about her and it is totally out of character."
Angelika Kluk is a student in Poland but had been working in Glasgow during her summer holidays.
She had bought her ticket to travel home to Gdansk.
Her sister said: "If anybody saw anything on Sunday afternoon please get in touch with police - anything could help.
"We do not know anything of her whereabouts. She left without any proper clothing or ID cards, not even her house keys.
"She is very serious, a responsible person, more than her age should allow her to be.
"She would not leave without notifying anyone and she doesn't do anything stupid, irresponsible or crazy."
Police have already carried out a search of the chapel grounds where Angelika had been staying.
On Saturday, she went to a golf range in the Bishopbriggs area with a man known as George, who is believed to have come from the Aberdeen area.
Police appealed for the man, also thought to be a member of the congregation at St Patrick's, to come forward.
They also asked for a man, Pat McLaughlin, who does odd jobs around the church grounds, to contact them.
Ms Kluk has a Scots boyfriend, a chauffeur in his 30s, and he is trying to help police with their inquiries.
Her sister, Aneta Kluk, says she is extremely worried
Ch Insp Elaine Ferguson said there was no reason at this stage to believe that the woman had either been abducted or was involved in human trafficking.
She said: "Angelika is a friendly, trustworthy and reliable person.
"Angelika's family and friends are becoming increasingly concerned for her safety."
Ms Kluk is believed to have her mobile phone with her but it is said to be going straight to voicemail.
She is described as 5ft 3in, of slim build, with long fair hair and green eyes.
She was last seen wearing a pink vest top, black combat-style trousers and possibly boots.
