A man has been arrested on suspicion of withholding information about the murder of a woman in west Belfast last weekend.

The body Jennifer Dornan (30) was found at her home in Dunmurry on Sunday.

Police believe the killer tried to cover their tracks by setting fire to her house.

Ms Dornan - a mother of three - had been on a night out with friends at the Devenish complex on Finaghy Road North last Saturday night.

Police say they left at around 1:30am and went back to a friend's house close to her own home.

At 3am she left her friend's house and walked the short distance home.
