Detectives investigating claims of widespread abuse at a children's home in Jersey are expected to break though into a second underground chamber this weekend.
Last night, officers finished clearing rubble from the first cellar at Haut de la Garenne and a specially-trained dog found traces of blood in a stone bath-tub.
Sniffer dogs detected two spots of blood in the large shallow concrete bath in a room underneath the building, where a child's skull was discovered on 23 February.
Some 100 people have come forward claiming they were abused at the former home, while some 25 people are being investigated as suspects.
Most of the alleged abuse is understood to have taken place in the 1970s and 1980s.
A team of more than 25 investigators has excavated the underground chamber and police believe there could be three more in the building, which closed as a children's home in 1986 and was later turned into a youth hostel.
