A 19-year-old man is due to appear in court accused of murdering and kidnapping two women who were found stabbed in a flat.
Kimberley Frank, 17, and Samantha Sykes, 18, were discovered at the flat in Barden Road, in the Eastmoor area of Wakefield, West Yorkshire, on Saturday morning.
Ahmad Otak, from Wakefield, has been charged with two counts each of murder, kidnap, false imprisonment and possessing a bladed instrument in a public place, West Yorkshire Police said.
He will appear at Wakefield Magistrates Court.
Earlier, bunches of flowers could be seen on the steps to the flats and cards had been attached to the handrail.
One bouquet had a card, which read: "Sammy, we will miss you sooo much. You were a great friend and will never ever be forgotten. We'll see you again one day. RIP."
West Yorkshire Police said officers were contacted by Kent Police after a 19-year-old woman in Dover raised concerns for the safety of the two women.
Officers went to the flat in Barden Road and discovered the bodies of Miss Frank and Miss Sykes, of California Drive, Horbury, West Yorkshire.
A post-mortem examination revealed the women died from stab wounds.
