A woman has been charged with arson following a blaze at a flat in Southsea.
Police said yesterday they had been called to reports of a domestic dispute at a home in Shaftesbury Road during which a fire was started.
A 36-year-old man and a 34-year-old woman were arrested on suspicion of arson.
But today Hampshire Constabulary said the man has been released without charge and will face no further action.
Caroline Clark, 34, of Shaftesbury Road, Southsea, has been charged with one count of arson with intent and has been remanded in custody to appear at Portsmouth Magistrates Court tomorrow.
