The father of Claudia Lawrence hopes today's arrest of a 46-year-old man by police investigating her disappearance "is another vital piece in the jigsaw", his spokesman said.
Peter remains very grateful for all the hard work that North Yorkshire Police are continuing to put in to finding Claudia.
It is to be hoped that this is another vital piece in the jigsaw of information that needs to come in to the police: it is much better if people volunteer information than wasting valuable police time in them having to find it out for themselves and then come looking for people.
