Fourth arrest over missing Ranya Alayed in Manchester 6 July 2013 Last updated at 12:39 A fourth person has been arrested over the disappearance of a Manchester mother-of-three who police believe may have been killed. Ranya Alayed, 25, was reported missing from the Cheetham Hill area on Tuesday but has not been seen since early June. One person was arrested on suspicion of murder and two over assisting an offender earlier in the week. A 38-year-old man from Salford was arrested on Friday on suspicion of assisting an offender. Police are still questioning the 33-year-old man previously arrested on suspicion of murder, and the 55-year-old woman and man of 64 held on suspicion of assisting an offender. Detectives said they were treating it as a missing person inquiry but said they could not rule out the possibility she has been harmed. It was extremely out-of-character for her to disappear in this way, they added. Ms Alayed moved to Manchester in January from the north-east of England.
