Eleven police were involved in a dawn raid on Rebekah Brooks's Oxfordshire home just six weeks after her baby was born, the phone-hacking trial has heard.

The former News International chief executive, who was not notified of the search, raised concerns with officers about the impact on the baby who "had been born prematurely", the jury were told by Jonathan Laidlaw QC, counsel for Brooks.

Her husband Charlie pleaded with police not to "bang on the door at 5am" on the door of his elderly mother who lived in an adjacent building in the former farm estate, Laidlaw added.

"Please don't bang on the door, I have no idea what the impact might be on her," Brooks asked police.

Rebekah Brooks also accused the police of leaking news of the raid to Sky News. "You've got our phones. It must be you, the police, who are leaking it to the press," she said, Laidlaw told the court.

Detective Constable Karyn Millar replied: "I don't remember that happening at all." She said she was "completely unaware" of an alleged leak and this was "the first I've heard of it".

During cross-examination, one of the police officers involved in the search in March 2012 confirmed that nine personnel from Operation Weeting were involved in the search along with two local Oxfordshire staff.

It was the second police raid on the premises, which had also been searched in July 2011 when Brooks was arrested.

Police seized two BlackBerry phones, an Apple Mac Book Air, two Apple iPads and four iPods from the house and outbuildings which included a laundry room, office, gym and stables.

Millar was asked by Laidlaw if the police had been aware there would be a baby. "I think we knew there would be a baby," she replied.

Laidlaw put it to Millar that Brooks had been "totally co-operative" and had put items belonging to herself and her husband Charlie into "separate piles" to assist them.

The court heard that the police had planned to search Brooks's London office in Marylebone on the same day but did not know the address. Millar confirmed to Laidlaw that Brooks had given her the address and the keys of the office to enable them mount the search.

Police had also searched Jubilee Barn in July 2011 when Brooks was arrested. The search took just 15 minutes. Detective Sergeant Jonathan Elwell told the jury there was no electronic equipment and no mobile phones on the premises. "[It was] what you would expect of a weekend residence or a holiday home," he said.

The jury heard that the main residential part of the home comprised of a kitchen/living room downstairs and two bedrooms and a bathroom upstairs. There were also outbuildings converted into a laundry, a gym, an office and stables.

Two police witnesses were asked whether there had been pornographic material discovered upstairs in the main bedroom. One police officer recalled that a pornographic DVD had been found while another recalled that it was a pornographic magazine. It was agreed that the item was not relevant to the search.

Both Charlie and Rebekah Brooks have been charged with a conspiracy to pervert the course of justice. They have pleaded not guilty.

The trial continues.
