Wakefield double murder: Victims were stabbed teenagers

The teenagers were found dead after police received a tip-off

Two young women found dead in a flat in West Yorkshire were both teenagers and had been stabbed, police have said.

Samantha Sykes, 18, and Kimberley Frank, 17, were found dead at the flat in Wakefield on Saturday after a tip-off from a woman in Dover, Kent.

A 19-year-old woman and a man aged 23 who were arrested have been released without charge but detectives are still questioning a 19-year-old man.

The bodies were found in a flat in Barden Road in the Eastmoor area.

The flat and the surrounding area were sealed off for forensic tests, which have continued through the weekend.

Post-mortem examinations carried out on Sunday evening revealed Miss Frank, who lived in Barden Road, and Miss Sykes, from Horbury, also in West Yorkshire, died as a result of stab wounds.

The three arrests were made by Kent Police in Dover, about 250 miles from Wakefield, after officers were called at 04:15 GMT on Saturday.

Kent Police said: "The 19-year-old woman raised concerns for the safety of two further women in West Yorkshire. Acting on that information, police in West Yorkshire found the bodies of two women at a property in Wakefield."
