Two women found dead at a suspected Midland massage parlour had suffered terrible head injuries, police disclosed last night.
A double murder inquiry was launched after the bodies of the women, one aged in her 20s, the second in her 40s, were discovered in Shrewsbury.
They were found lying next to each other on the floor of a business that officers believe may have been used as a massage parlour.
Detective Superintendent Andy Rowsell, who is leading the investigation, said the women had suffered "significant head injuries".
He said: "It is a dreadful offence and a dreadful occur-rence. It needs to be investigated thoroughly and we will do whatever is required at the scene.
"Clearly, there is someone who is capable of committing this degree of violence and we are doing everything we can to find that person and arrest them at an early stage."
The alarm was raised by two members of the public who discovered the victims and flagged down a police patrol at about 2.45am.
Officers sealed off the area around the business in Frankwell, a road which shares a name with the surrounding neighbourhood. They also closed the nearby Welsh Bridge.
Police said the business was registered as a health studio, but admitted they were trying to find out if it was used as a massage parlour.
They said if it was being used as a health studio, it should have closed in the early evening.
Officers are scouring CCTV footage from the busy Frank-well area, a popular night time destination for drinkers, in the hope of identifying the killer.
More than 40 officers from West Mercia Police are now involved in the investigation.
Police want to speak to anyone who was in the area between Saturday afternoon and 2.45am yesterday.
He said that no murder weapon had yet been found.
