Two women held over death of Herefordshire pensioner
Two more people have been arrested by police investigating the death of a 75-year-old man from Herefordshire in November 2000.
The women, from Leominster, are being questioned as part of an investigation into the death of Albert Ryall, who was found dead at his home in Risbury.
They have been arrested by West Mercia police on suspicion of perverting the course of justice.
On Tuesday four men were arrested on suspicion of manslaughter.
The police reopened the case in May and a reward of £10,000 is being offered for information.
