London, Sept 17 : Two young women were found hacked to death in a 'sustained and violent' attack at a luxury apartment block in Birmingham.
The women, in their early twenties, were discovered by the concierge who forced his way into the 200,000-pound flat.
He had been alerted by worried relatives who had failed to make contact with the pair.
Residents have claimed that the women had been working as prostitutes and were possibly killed after a 'sex party'.
However, police said they were unaware of any vice link 'at this stage' but admit that they there was no sign of a forced entry.
Cops said the victims, thought to be Iranian, suffered 'horrendous' injuries in a frenzied attack that involved knives and blunt objects.
Detective Chief Superintendent Dave Mirfield, head of West Midland Police's major investigation unit, said: 'It was a sustained and violent attack.'
Forensic teams found blood spatters in nearly every room of the murder flat. It could mean the victims were chased around as they were attacked.
"The inside was like something out of a horror movie. There was blood up the walls and over the furniture," the Sun quoted a source, as saying.
"Blood was also found on the landing and in the car park of the apartment block - where the killer presumably drove away.
"The frenzied nature of the attacks could point to the killer being on drugs," the source added.
The bodies had not been removed from the flat as forensics officers worked inside.
A 28-year-old man from the city, who is understood to be known to the women but not related, was arrested following an all-ports alert as he attempted to board a ferry in Dover, Kent, 12 hours after the bodies were discovered.
The flat is on the top floor of the five-storey Jupiter block, close to the city's Broad Street clubland.
