TWO robbers involved in stealing #1m worth of jewellery and cash from TV star Cilla Black are thought to be from Liverpool.

The gang of three men held a knife to the throat of Cilla's son, Jack, during the raid at the television presenter's mansion near the village of Denham, Bucks, over the weekend.

Thames Valley Police detectives have now pieced together descriptions of the men from his account of the robbery.

Two of them spoke with Liverpudlian accents and the other is believed to be of Middle Eastern or Mediterranean origin.

They were wearing identical black clothes, thought to be shell suits, with piping down the arms and legs and black woollen balaclavas .

The dark-skinned man was about 6ft tall, of athletic muscular build and seemed to be older than the other two, possibly in his thirties.

The two Liverpool men men were white, in their twenties, about 5ft 10ins tall and stocky.

Cilla said it was "heartbreaking" to lose the items of jewellery, including gifts from her late husband Bobby Willis, but it did not compare to the ordeal Jack, 22, had endured.
