A couple lost precious images of their newborn daughter when their home was burgled.
The footage was stored on a JVC camcorder and a laptop computer which were among a number of items stolen from their home in Loughborough Road, Birstall.
Pc Nathaniel Lockley said: "The parents have been left heartbroken. Images like this cannot be replaced."
The intruders forced their way inside through a patio door between noon and 2.15pm on Monday, December 10.
They also stole jewellery, including a silver Tag Heuer watch with a black face; a silver square-faced Diesel watch with a green face; a platinum ring with diamond shoulders and a central pearl; an engraved gold chain and gold pendant, a fine gold chain set with blue stones; a silver necklace with a small diamond encrusted heart; a pair of oblong earrings with diamonds in the centre and a silver box engraved with flowers.
Also stolen were a black Apple iPad, an Apple TV, a silver Bose radio and a white Xbox.
Anyone with information can call Pc Lockley on 101 or Crimestoppers, which is anonymous, on 0800 555 111.
