A 26-year-old man has been charged with arson after a Hamilton flat was set alight in a domestic dispute.
Police discovered the fire after they were called to the dispute at a block of flats in Frankton about 1am.
Officers talking to the female victim outside her flat noticed a strange glow in the window, and found a couch set alight and the lounge well ablaze.
Residents of the other flats were evacuated.
Police said the flat in which the fire was lit was badly damaged, while another flat suffered serious water damage in efforts to save the building.
