Police searching a former children\'s home in Jersey have asked for more investigative staff to help with the operation.It follows last weekend\'s discovery of a child\'s skull at Haut de la Garenne and police are now excavating seven sites which were identified by a sniffer dog specially trained to find human remains.More than 160 former residents of the home, which closed in 1986, have come forward with abuse claims dating back to the 1960s. Victims claim rooms at the site were used for abuse and have described being raped, drugged and flogged.Jersey Deputy Police Chief Lenny Harper said members of the public are continuing to make allegations of serious sexual crimes, and a request has been made for a further 12 staff to assist with the investigation.More than 70 phone calls have been received in the past few days relating to alleged abuse at the home involving over 40 suspects.The excavation site is in a stairwell approximately 20ft long by 8ft wide. Teams of between two and four forensic experts have worked on the area every day since the operation began.Currently the two working on the site are an anthropologist and an archaeologist. They have removed the top layer of concrete and have excavated between six to eight inches of material working in excess of 30 hours since Saturday.Mr Harper said they have now been given very old plans of the building which seem to indicate that what they have been referring to as the \'cellars\' could originally have been the ground floor.He said searching the area is a very delicate operation, and the investigative team is determined not to lose any evidence. Police have no evidence whatsoever of any government cover-up in relation to the abuse claims, he said.Work has started to clear one of the three underground chambers and officers have found two \"significant\" items which they said corroborate victims\' claims of being abused and locked in solitary confinement.They anticipate work in the first chamber will take most of the week before they attempt to break in to the second.They are also searching for a third chamber after being contacted by a former member of the care home staff and have started a new dig in a field behind the main care home building.Mr Harper would not say what the items are and would not confirm widespread reports that one was a bath.He said: \"They corroborate evidence of offences in the cellar. They\'re items that victims said were in there when offences were committed against them.\"Mr Harper said detectives have taken statements from witnesses as far away as Australia and Thailand.The NSPCC said that it had received more than 100 calls from adults reporting allegations of childhood physical, sexual and emotional abuse in Jersey Abuse, Body, Care, Child, Home, Injustice, Now, out, Speaks, Stop, Victim
