A 13-year-old boy was being questioned today in connection with the death of a woman found seriously injured at a house.
Police discovered Dawn McKenzie, 34, at an address in Devaron Crescent, Hamilton, South Lanarkshire, at around 8pm on Friday.
She was taken by ambulance to Hairmyres Hospital in East Kilbride, where she died a short time later.
Her relatives said they were "devastated and numb with grief".
The teenage boy is being held in police custody following his arrest.
He is expected to appear at Hamilton Sheriff Court tomorrow.
Strathclyde Police said a full report will be sent to the procurator fiscal.
Ms McKenzie's relatives have paid tribute to the "loving" woman and said her husband was in a state of shock.
In a statement issued by police on behalf of the McKenzie family, they said: "The McKenzie and Byrne families are devastated and numb with grief over the tragic loss of Dawn.
"Her husband Bryan is badly shocked and unable to speak to anyone at this time.
"Dawn was a loving wife, daughter, sister, niece, aunt and friend who will be sadly missed by everyone who knew her. She was a nursery nurse, nanny and helped mothers and children throughout her working life.
"The families would like to thank everyone who has helped them at this difficult time and for the messages of sympathy and support which they have received."
