Two former child residents of Cosham's Children's Cottage Homes claim children were taken from their dormitories during the night and disappeared.
Reg Tugatt, 59, a former resident of Cosham's Children's Cottage Homes says he saw 'suspicious holes dug'.
Reg has given police a map showing holes dug in the vicinity of Cosham's Children's Cottage Homes - in a wood and near an orchard. (Police handed map of holes at child abuse scandal home / Second 'abuse' victim speaks out)
Reg said he was taken into care at the home in 1956, aged eight, and stayed there for three years.
A spokeswoman for Hampshire Police said: 'We have no plans to dig up any sites in Portsmouth and continue to hold the position that there are no links between allegations made in reference to the Children's Cottage Homes in Cosham and the ongoing investigation in Jersey.'
Les Cummings, 63, is campaigning for an apology from Portsmouth City Council for the abuse he claims to have at the hands of his foster father and at the Children's Cottage Homes.
A total of 21 men and women told detectives they suffered physical and sexual abuse as children at Children's Cottage Homes.
A 78-year-old woman from Devon was arrested on suspicion of indecent assault but when police passed the file to Crown Prosecution Service lawyers they decided there was not enough evidence to charge her.
Les Cummings went to police to ask them to look again at their earlier investigation into the claims of 21 men and women.
The Crown Prosecution Service examined allegations against the centre but decided not to prosecute.
Both Reg and Les claim that a number of children were taken from their dormitories during the night and disappeared.
