Police said there were six residents at the hostel where Albert died

Detectives in Lancashire and Scotland are carrying out a joint inquiry into the deaths, which all happened in women's refuges.

On Friday, detectives appealed for information about the death of 10-month-old Albert Rogerson in December 1973.

His body was found at the Parkinson House refuge, at West Cliff, Preston.

It is believed Albert had been staying at the hostel prior to his death.

Confidentiality respected

Detective Superintendent Paul Buschini said there were six women staying at the hostel at the time of Albert's death, five of whom detectives are trying to trace.

"It is important that these people are traced as they may hold vital information, which could help this investigation," he said.

"We appreciate the need for confidentiality of the hostel residents and will continue to respect the wishes of the individuals concerned."

Records from the hostel - which was run by Preston Moral Welfare Council - show the women's names were Christine, Patricia, Delia, Norma and Gabby.

However, no surnames were recorded and the names could have been false.

"The investigation is being conducted in conjunction with the Lothian and Borders Police, who are investigating the circumstances surrounding the deaths of a further six children in their police area prior to 1973," said Mr Buschini.

Anyone with information regarding Albert's death should contact police in Preston or ring Crimestoppers.
