The sister of a Scottish woman allegedly murdered in Pakistan broke down as she called for justice for her family.
Mumtaz Sattar, 38, from Port Glasgow, Inverclyde, died shortly after arriving in the country's Punjab province last month.
Her husband Abdul has been arrested in Pakistan.
He had told police he and his wife were drugged and attacked by two men during a taxi ride on the way from the airport to see his parents on September 21.
The case, including the family's concerns about aspects of the investigation in Pakistan, were discussed at a meeting last week involving the new governor of the Punjab region, Mohammad Sarwar, Mrs Sattar's brother Sarfraz Ali and Glasgow-based solicitor Aamer Anwar, the family's lawyer.
Doubt was cast on Mr Sattar's version of events and he has now been arrested along with three other men in connection with the death, Mr Anwar said today at a press conference in Glasgow with Mrs Sattar's three sisters and brother.
The three other men arrested are linked to a white car that Mr Sattar said was a taxi he hired at the airport.
Police allege that the car is not a taxi and that Mr Sattar knew the men who were travelling with him.
The Sattars, who had been married for 14 years, have two daughters, aged ten and 13, who are being looked after by family in Scotland.
Speaking at the press conference, one of Mrs Sattar's sisters, Mehnaz Jilani, said: "These past three weeks have been full of shock and disbelief for the whole family.
"We do know that we have a long way to go yet but the initial version of the event just did not add up, hence all the help drafted in to bring out the truth."
Speaking through sobs, she added: "Our main focus is all on our two nieces now, a big part of our family life is now gone, no more visiting each other, no more phoning each other, no more texting each other, no more going out, no more big sister. All we are asking for is justice, that's all we want."
The four arrested are expected to spend about two weeks in jail in Lahore until formal charges are brought.
Mr Anwar said: "I can advise that Abdul Sattar has now been formally arrested and is presently in custody at Nankana district police office.
"Three other suspects have also been formally arrested. These men who were on the run following the recovery of a white car on Sunday are allegedly linked to the white car and to Abdul Sattar.
"Critical to the investigation has been the recovery of the white car which Mr Sattar claimed was a taxi and used to transport him and Mumtaz from outside the security perimeter of the airport in Lahore.
"Police have confirmed this car is not a taxi and that Mr Sattar was seen on CCTV footage from the airport greeting the males from the car."
