Police searching a Jersey, U.K., youth hostel after the discovery of a child's remains have put up more tents to expand the area they're combing — but say they do not know if they will find more bodies.

The widening of the search area at the youth hostel at St. Martin parish in Jersey follows the initial find by a sniffer dog previously used in the hunt for missing British toddler Madeleine McCann.

The dog led police to the remains of a child at the former Haut de la Garenne children's home on Saturday.

A further six sites are being looked at in the hostel, which has been at the center of a child abuse investigation since November.

Jersey's deputy chief police officer, Lenny Harper, said the force was treating it as a major crime and could not rule out the possibility of more bodies.

But he told reporters outside the building: "The truthful answer is we just don't know."

The investigation began when a number of former staff members were arrested on suspicion of pedophile crimes.

The States of Jersey Police first started a covert inquiry into the history of the home, speaking to victims of alleged abuse.

Mr Harper said several people had come forward claiming they had been abused as children, but their complaints had been ignored by different agencies on the island.

He said his officers were investigating the reasons why the complaints were not dealt with, but added there was no evidence of a cover-up by the Jersey government.

The Haut de la Garenne closed as a children's home in 1986.

The Youth Hostel Association said the incidents being investigated by police pre-date the building's use as a youth hostel by two decades.

The youth hostel was opened in 2004.
