A documentary by investigative journalist Donal MacIntyre examining the disappearance of York chef Claudia Lawrence will air this weekend.
Miss Lawrence, a chef at York University, was 35 when she went missing on her way to a 6am shift at work in 2009. She has never been found and police believed she was murdered.
A file of evidence has been submitted by police to prosecutors in relation to four men arrested on suspicion of her murder.
