Urfan Sharif, the wanted father of dead British girl Sara Sharif, sent a message to businessman Nadeem Riaz just before 10pm on August 8.

The reason for that became clear after Sharif and others had made it to Pakistan, and police found Sara alone and dead in the family's home in Woking, south of London.

According to The Sunday Times, Riaz owned a money transfer business and ad hoc travel agency.

He had known Sara's father, Sharif, for 11 years.

"He said he needed to book as soon as possible," Riaz told The Times, describing events that led to Sharif fleeing to Pakistan, where he has since gone to ground.

"I asked why and he said his cousin had passed away in Pakistan," he said.

"He sounded normal. No different to his usual self."

During the conversation, Riaz asked what type of tickets Sharif wanted.

He responded with just two words: "One way."

Minutes later Sharif wanted an update.

So he sent a message on WhatsApp at 10.12pm: "Any luck?"

Riaz managed to secure eight tickets for Sharif, at a cost of around $10,100, and the group boarded a flight from Heathrow to Islamabad at 2pm, on August 9.

Travelling with Riaz were his partner and Sara's stepmother Beinash Batool and his brother Faisal Malik.

Riaz's five children, aged between one and 13, also flew into Pakistan.

After landing in Islamabad, Sharif called police and told them Sara's dead body was at the family home.

Police rushed to the address and she was found with extensive injuries, which a post-mortem examination deemed had occurred over a sustained period.

Pakistan police have been trying to locate Sharif and the others since.

A cousin of Batool, Sara's stepmum, urged her to hand herself in to police.

"Beinash should come back to the UK," they told Sky News.

"I don't know where she is. But I'm worried about her. I'm worried about her kids.

"She should come back to the UK, go to the police and tell them exactly what happened."

"I don't know – my family don't know – what happened. It could have been an accident, a misunderstanding."
