LONDON , England ( CNN ) -- Police on the picturesque island of Jersey in the English Channel detained a 68-year-old man Tuesday as part of their investigation into alleged abuses at a long-closed government-run children 's home . A woman walks past the Haut de la Garenne children 's home . Spokeswoman Louise Nibbs said the man was helping authorities with their inquiries into `` a number of historic rapes and indecent assaults . '' But , Nibbs added , the man 's detention was not `` directly related '' to the Haut de la Garenne children 's home . Rather , he is part of a wider inquiry into abuses that authorities are investigating , she said . `` We can now also confirm that the alleged offenses in question took place in the 1960s and 1970s , '' she said . `` We are not able to say at this time where the offenses took place . '' Nibbs did not release the man 's name or disclose any other details . The man has not been charged with a crime , Nibbs said . Jersey is a British crown dependency , located 14 miles off the coast of Normandy near France . In January , police arrested another man -- a former warden who was charged with three counts of indecent assault on underage girls in the late 60s and early 70s . The man , 76-year-old Gordon Wateridge , has not entered a plea yet , Nibbs said . The announcement in January that fragments of a child 's skull had been discovered under a stairwell in the building has sparked more than 160 allegations of child abuse there dating back to the 1960s , authorities say . The building opened in 1867 and housed up to 60 children at any one time . It underwent several renovations and closed in 1986 only to reopen as a youth hostel in 2004 . Possible clues to the abuse alleged to have occurred inside include writing found on a wall that `` refers to somebody being bad , '' Jersey Deputy Police Chief Lenny Harper said in February . `` We have no idea at the moment who put it there or , indeed , how long it 's been there . '' Police said much of what they found , including shackles , matches accounts given by witnesses . Several former residents allege they suffered physical and sexual abuse in a storeroom . Police suspect there could be four bricked-up chambers underground . Several alleged victims have talked about abuse occurring in a large concrete trough in the basement , which was originally the first floor of the building . In February , authorities said they had compiled `` well over 40 '' suspects who are alive , and a number of others who are dead . The investigation has taken officials to Australia , Thailand , Germany and the British mainland . Some of those who have reported abuse have taken their complaints to the news media . `` There was one occasion , in the sick bay , where I was made to fondle another boy -- if you did n't , you were threatened you would n't come out alive , '' said Carl Denning , who said he was taken to the home at the age of 5 and said one of his friends committed suicide after being raped there . `` You 'd go to bed at night , sleeping , and all of a sudden your arms would be held down and the next thing you know you 're getting raped , '' recalled Peter Hannaford , who spent the first 12 years of his life there . `` You were subject to constant abuse . ... It was every night , and you were scared to go to bed . '' Stuart Syvret , a local politician , told CNN the building had long been known `` as a place where young boys were punished severely , where they suffered . '' He alleged a `` long-established culture of covering up alleged abuses '' -- a claim the local government denies . The investigation began in 2006 , when police were alerted to the possibility that pedophiles had worked at the institution . That led to the discovery of the skull fragment . The institution housed wards of the state -- primarily neglected and abandoned children . A remand wing housed children who had been convicted of crimes . The allegations mar the carefully cultivated image the island 's elite have tried to project . Jersey 's beaches have made it a big tourist destination , and its offshore banks have made it a tax haven and a playground for the rich . Eleven miles long and 9 miles wide , the island is populated by about 80,000 mostly white , affluent residents . Heavily influenced by the French , the largely autonomous island has its own legal system and its own currency . London manages only its defense and foreign policy matters . E-mail to a friend .
