<p><br /> Detectives have been granted more time to continue questioning Joanna Yeates's landlord on suspicion of her murder.<br /> </p><p><br /> Chris Jefferies, 65, was arrested yesterday morning and a magistrate tonight granted Avon and Somerset Police an extension to hold him beyond 7pm.<br /> </p><p><br /> The development came after officers spent the day talking to Peter Stanley, 56, a neighbour of the retired public school teacher in Clifton, Bristol, who said he and Mr Jefferies helped start Miss Yeates's boyfriend's car the day she vanished.<br /> </p><p><br /> Mr Stanley recalled how he and Mr Jefferies used jump leads to start Greg Reardon's car, sending him on his way to Sheffield.<br /> </p><p><br /> "It was a non-event at the time, but absolutely poignant now - what if we didn't get the car to start?" said Mr Stanley.<br /> </p><p><br /> Hours after successfully starting the car, Miss Yeates, a landscape architect, disappeared and her snow-covered body was discovered more than a week later on Christmas Day.<br /> </p><p><br /> Mr Stanley, who lives in a flat in the mansion to the right of Mr Jefferies' in Canynge Road, Clifton, is being treated by police as a witness, they confirmed tonight.<br /> </p><p><br /> He drove away from his home in his maroon BMW with a detective and returned later in a marked police car before officers left him.<br /> </p><p><br /> Mr Stanley said he did not think Mr Jefferies spoke to Mr Reardon about going away for the weekend, and added: "I wouldn't say there was anything tense between them."<br /> </p><p><br /> He said: "I had only just charged up my car because it didn't work when I had gone to see a friend.<br /> </p><p><br /> "I got a phone call from Mr Jefferies. I was asleep at the time and it was early evening.<br /> </p><p><br /> "He asked if his tenant could borrow my jump leads.<br /> </p><p><br /> "I think Chris Jefferies wanted to borrow my car, but I said I didn't want to take all the power out of it.<br /> </p><p><br /> "So he said 'Fine', and he then brought his car - I think it was the Chrysler.<br /> </p><p><br /> "I met Greg and Chris Jefferies at the edge of the property and walked toward the car.<br /> </p><p><br /> "I got Chris Jeffries to position his car so the bonnets were alongside each other.<br /> </p><p><br /> "Greg's car was in the gutter of the road, and Chris Jefferies' car was in the road."<br /> </p>
