There is no mention of a phone call to Witham In PC Wests August 9th statement. It only appears in Wests September 13th statement.
I have quickly skimmed through the September police interview's with Jeremy. Unless I have missed it the police never put the question to him. (please correct me if I am wrong)
We are led to believe that Jeremy had told PC West he rang Witham. But PC West fails to record this in his statement. Then Jeremy denies calling Witham.
Since West never recorded this alleged conversation during his August 9th statement. Plus there is no good reason for Jeremy to deny calling Witham. I believe the answer is no.
Here is RWBs diary entry for the 30th of August. 
Local people know that Witham is closed from 2-6am.
Jeremy Bamber was a local.
He knew Witham was closed between 2-6am. I don't understand why you are making so many excuses for him David? You need to look at ALL the evidence. ALL the evidence shows withoutdoubt Jeremy Bamber is guilty.
PC West explained during the trial why the Witham phone call wasn't in his first statement. There's no conspiracy.
I agree with Caroline that when Jeremy phoned the police he told him it was his sister. And as has been pointed out during his interviews, he slipped up big time over the questioning of
Sheila &
she has. He couldn't keep up the pretense.
His conversations with police outside the farmhouse show how he set the scene. His witness statements attempt to solidify his stories but his plans back fire. Did you notice in his statement how he said his father paused before speaking? What a load of cobblers! He over egged it.. There was no phone call from his father! His father was already deceased.
Remember how the dog was whining when he and the police arrived at the farmhouse? Jeremy made a point of stating the dog never did that.
The dog was whining because his master had been killed.
Only an idiot would phone a police station that all the locals knew was closed between 2-6am.
