Police search children's PRAMS as Kate, William and Harry join the Queen for post-Christmas Sunday church service at Sandringham

Officers were spotted checking toys, bags and the linings of several pushchairs (left) as residents lined the street in a bid to get a glimpse of the Royal couple, who attended the service with the Queen and Prince Harry. They also patted down coats and examined rucksacks, including a Star Wars bag with a picture of a Stormtrooper on, which was carried by one little boy (inset left). A young girl wearing a pink padded coat was also checked by an officer using a hand-held security scanner as she waited patiently on the gravel. The Duke and Duchess, who arrived with Prince Harry (right), walked to the service and were happy to chat to crowds of well-wishers as they made their way through the estate.
